Sliceform basic

1, What is sliceform?

Sliceform is a method of modeling a 3D model by piecing the pieces together. The pieces are tied together by many groove. It is used in many works by pop up artists like Yee design, Marrivi, Hiroko…

Here are some sliceform models:

Sliceform-basic-1 Sliceform-basic-2

The images above is just basic geometric model and couldn’t show all beauty of this method, artist usuallt add more detail and modify them into delicate productions like following:

Sliceform-basic-3 Sliceform-basic-4 Sliceform-basic-5

2, So who invented Sliceform?


Sliceform techniques derived from a mathematician called Olaus Henrici who taught in London in the late nineteenth and early twentieth century. He used the cross-section model of quaternary surface, which is similar to a spherical, or oval, or parabolae hyperbolae.

That day the method used to create these models was not fully exploited, however initial application of sliceform is to hold fruit …; D

But then, Sliceform started being used in geometry simulation teaching. Science Museum in London still retains Sliceform models from the 19th century until now.

3, Getting Started with Sliceform

The following models are simple sliceform models for beginners to guide you how to assemble and attach to the card. They seem to be so simple and do not take much time, so some people might think they’re bored. But actually it’s totally a misconception. Just try them before challenge yourself at higher level.

_Sliceform Super-egg


_Sliceform hyperbolic paraboloid


The patterns of these models can be found here

You can find more advanced patterns on website

4, How to attach pieces to form sliceform modeling?

In most cases, you should cut 2 pieces which will be paired together, then cut the grooves and assemble them. Some models have numbers in the diagram to display the order of the pieces assembled.

Some Slideform pattern is accompanied by assemnble diagrams which helps us easily imagine the structure of the card so that it can be folded easily.

A typical assemble diagram:

Sliceform-basic-9 Sliceform-basic-10

When cutting the slideform pattern you should cut carefully; especially grooves, as if cutting unevenly between grooves can make them not fit together. In addition, it can make the card inflated. A well-cut pattern when folded will fit completely and the card will be flat.

Another important tip is that when cutting the grooves, you should cut them wide enough to fit the thikness of the paper. If they are too large, the model will collapse easily, especially when building complex patterns. In contrast, too small grooves can make folded form blocked.


Paper cutting and its history

Paper cutting is a type of craft aged hundreds of years, but it is still very popular today. The following brief description will generalize somewhat about the development and history of this art.


History of paper

Before the invention of paper, man has recorded the documents which are figures drawn in the caves or carved on clay tablets, and then in next period people used leather, carpentry to store the document. Since the Chinese invented paper in 105, paper began to be widely used in China, and until year 750, new paper production techniques spreaded to Samarkand through Chinese prisoners in a border dispute. Paper was brought to Europe from the 12th century through the cultural exchange between Western Christianity and Eastern Arabs as well as through Spain in Islamic periods.


Paper Cutting Art


With the introduction of paper, paper cutting art has appeared almost the same time. Soon it became very popular in China, especially in the Song Dynasty (960-1279). The first artist is perhaps the members serving in the court; paper cutting has quickly spread and become a folk art, it was used bu Chinese for various reasons such as decoration for homes, lanterns, festivals, etc. The patterns made from paper are also used as decoration for sedan chairs, boxes, chests, and disk). The model for the Chinese paper cutting is mainly taken from Chinese mythology. Tissue paper (a very thin paper) and parchment are often used for this art.



Follow the footsteps of merchants via the Silk Road, Chinese paper cutting art first came to Austria under the gift to the king in the 15th century and later spread throughout Europe. After being “exported” to Europe, it has become a popular traditional culture, especially in Germany, Poland, Netherlands, Switzerland and some other countries. The initial work is often “palm-sized” and include small landscapes and decorative floral motifs; paper cutting pattern at that time is often used to decorate the interior because it is cheaper than the traditional carvings. In 16-17th century, paper cutting art began to spread out and its name is different depending on the country.

In Poland (wycinanki) paper cutting peaked between 1840 and the start of World War I. The colorful works made with sheep shears. Even today Polish paper cutting is still made with raw sheep shears and mainly for home wall decoration. Most works have the shape of a wheel or square, roosters and hens, the fairy tale in which a number of common motifs. Some artists often use colors in their designs using multiple sheets of paper glued to each other.


In German, paper cutting called Scherenschnitte. Scherenschnitte appeared in Germany in the 16th century and today remains a popular art in the German culture. The work is often inspired by the Bible, the poem, the romance story…

Papercutting art in the United States began with German immigrants in Pennsylvania, as well as others who have taken their craft to the US from Europe. Although this at has never attract large number of participants in the past, recently it has been a revival by paper cutting enthusiasts and collectors who are looking for ancient works .The paper cut Papercutters Guild of America (GAP – www.papercutters. org), is an association of the largest paper-cutting artist in USA with hundreds of members around the world. GAP members includes from amateurs to professionals, and from the beginners to the true artists. There are even a number of participants who do not not cut paper, but only engage in the collection to study tradition papercutting. There is no requirement for members. Everyone is encouraged to start with the talent they have, and develop skills and their art as part of a paper cutting community.



Paper cutting in Mexico called Papel Picado, or “perforated paper” and originated in ancient Mexico. The Aztecs used berries and bark to make a rough form of paper, called ‘Amatl.’ In Mexico, during the mid-1800s, people had to purchase goods from “Hacienda” (a type of form as the subsidized sales in Vietnam) and here they begin to access the paper from China. In recent years, tissue paper has become primarily paper used for Papel Picado. Artisans will create 40 to 50 layers of different colors sheet of paper silmutaneously and they use fierritos (looks like the skew for kebab skewers), or opaque. When completed, the work is hanged on the wire to make long banners used for weddings, religious festivals, and other special events. Designs include birds, flowers, and animals. Skeleton is also used to celebrate the “Day of the Dead,” a special celebration in Mexico.


Papercutting art has become part of many different cultures, including Jews. Traditional paper cutting of the Jews has been used for people to decorate ketubahs (contract prenuptial agreement. It is considered part of traditional Jewish marriage, Ketubahs outlines the rights and the groom’s responsibility, in relation to the bride) and holidays (Shabbat Mitzvah, and Passover, etc.); and is hanged appreciatedly as works of art in the homes of the Jews.



silhouette is the image of a person, animal, object or scene represented as a solid shape of a single colour, usually black, its edges matching the outline of the subject. It is a form of paper cutting. The first silhouette in Germany has been made about 1631. For the first time, the shadow of your loved ones have been preserved. It reflects the desire to capture portraits of people using a simple paper cut.


A silhouette portrait can be painted or drawn. However, traditional methods of creating portrait silhouette is cut from black cardboard light, and mount them on a light background (usually white). A portrait artist will cut the traditional silhouette portrait of a person within minutes.


Japan is one of the countries influenced by Chinese paper cutting art. But the Japanese have developed it into one of the national unique art and culture. The term of kirigami is commonly used for this art. In the Japanese, “kiri” means “cut” and “gami” means “paper. Typically, a kirigami work is started by folding into several parts, the artis would then unfold the paper after bearing the image of a snowflake, symmetric polygons, or the flowers… (the common is that they are symmetric through the center). Such works are called Mon-kiri.



Mon-kiri, differ from the rest of Kirigami is Kirie, Kirie (切 り 絵) is an expression of an image to be cut with scissors or a knife in a black paper. Once completed they will attach the cutout on a white background to create a contrast, which gives the impression to viewers like a real painting. Kirie originally used in Catholic ceremonies in Japan. Today, Hina Aoyamal is the most famous artists of this art. She has published many books guiding Kirie, if you are interested can find purchase on


KIRIGAMI – Easy or Not ????? Level of players

What is kirigami?

Firstly, at the very beginning, let us show you some basic concepts of kirigami.

The term of “Kirigami” originally used in paper-cutting art of Japan (of which the main producing process is folding paper into sections, then trimming to create symmetrical cut paper pattern over 1 center). On 10/12/2010, the fanpage and club of 3D pop up card and paper cutting in VN was established on FB, using the term in refer to all type of paper cutting (perhaps because it is compact, rhyme and easy to read: D). Therefore, term of kirigami is commonly used at present, does not refer to paper cut art comes from Japan only. Because in fact, very few players in Vietnam followed trdiational Japanese style of kirigami (even Kirie – Japanese paper cutting painting, seems not very popular.)


In general, paper cutting art is basically divided into:

          -Bearly paper cutting: or ZERO degree kirigami. There are several sub categories in this type as silhouette, stencil, china paper cutting… This type is considered cornerstone for the latter development into other types.

          -Pop-up cards: 3D cards that can be folded into flat surface. There are several methods to creat 3D cards that can be opend in range from 0 to 360 degree. The content in such cards is ussuallly very abundant, basically devided into smaller groups:

               + Outline cutting: It is popular with cards designed by using triangle method combining slice form or multi layer. Glue is usually used to connect parts of card.

               + Pop up kiri (all motifs are created by cutting, color printing is limited or nod used). It’s common with slice form and multi layer, triangle style is relatively rare. Glue is not used. Latches or interlock links are usually used in such types.

               +OA (origami architechture) is presenting architecture on paper, often used sliceform (180 degree) or multilayer (90 degree). It is considered a typical group in pop up kiri.

So how to conclude? Is kirigami easy or not?

It’s hard to find out a general anwer for this question. There are many players said it’s easy, but no less than than say it’s too difficult, it depends on your own. Thus, this post is mainly to discuss the level of kirigami players, hope that it can be a reference to help you evaluafe your skill yourself. This ranking is for all categories that I presented before, because writer couldn’t have sound knowledge in all of them.

Level 1: Players that can cut based on available patterns.

In kirigami, the card are usually cut out and finished by the author, then there will be 1 cutting template (pattern) provided to people based on that; they then cut the lines on the paper to complete (0 degrees), or then fold to complete based on a sample of finished products (pop-up). It’s pretty easy for you to reach this level, because anyone can cut the lines on paper. Workmanship is classified based on the cutting speed and sharpness of line cutting, ability to folding 90 degree cards, OA, or attach precisely 180 degree pieces sliceform. Proficiency in this level, you have a clear understanding kirigami then. And it also decided your passion to kirigami, you’ll probably give up because it’s too boring, easily, because all you need is simply downloading pattern, printing on paper, then cutting and finishing, (nothing can be easier, right?). But there are also players who learn deeper in this subject, and move on to Level 2.


Level 2 refers to people who can redraw other’s work.

First of all, write would confirm that, redrawing a pattern is not a challenge, it does not require a professional drawing skill, or skillfulness. The only requirement is that the understanding of basic principle of kirigami, to explore the method used by the author, then finish the pattern is too simple. And to understand the principles, avoiding errors in the rendering process, they should have experience in cuttingand proficiency in cutting ability. Once player have mastered this level, usually forwarded to the next level, few people stop at this level without progress further.


Level 3 includes those modifying pattern of others into their style.

Based on available ideas and methods from their predecessors, players can change according to their own ideas. It requires greater creativity than just redrawing of others. With this level, players partly reflect their own self through work, and can also help distinguish themselves between many other kirigami fans.


Level 4: Realize your own ideas.

After redrawing the pattern of other authors, having ability to modify according to their own pattern, then gradually, players can also express their own ideas based on past experience. At this level, the individual mark is expressed most clearly, because it contains the whole idea as your understanding of kirigami, the auxiliary talents like drawing, matching, logic … to achieve this level, then you have one fairly broad understanding of kirigami, for each category, the simple, the complexity of each method, and choose the method and style appropriate for the charcoal. Once mastered it, you can flatten almost the whole world in your way, can produce your own style, his own image in the community kirigami. Among those who express their own ideas through works in kirigami, there is obviously some people that still keep the style  of the author before who they go under, and sometimes difficult to escape from that style, like a trail. But surely, there will be no doubt about love and passion for kirigami of those players 🙂


Level 5: Realize the idea of ​​other people

You may be wondering, why level 4 is not the highest level, which is the highest level. In my point of view, then at level 4, every work is customized to author’s style, thus no matter it’s beautiful or not, it’s still achievement of author. But at this level, on the other, to express the idea of ​​other people, other people’s mark is what left on the paper, combining author’s style and other’s idea into the design is not an easy task, especially when the idea was to not have a deep understanding of this subject. More importantly, when the work is created, others will be given, give damn it, the designer will have to accept this, like it or not. So surely it is harder in comparison with developing author’s own idea.

WAY TO SUCCESS – Pop up card pattern



“Only those who dare to fail greatly can ever achieve greatly.”

Do you take any risks in your life? Do you set your goals high, and then work hard to reach them? If not, how much progress can you be making? Of course, there is always a slight chance that you might fail, but you will have learned invaluable lessons along the way. So don’t be scared to have high expectations for yourself. If you have reached one goal, set another one, one that might be even more of a challenge. For example, maybe you want to run a marathon, but are too scared to make this your goal. You are allowed to start small. Start by just running a local 5k, and then a 10k. Smaller victories along your path will lead to greater ones.

We attach here a new pattern from author Tien Phuong. Hope that you will always keep your passion and strong desire to achieve success in the future.

Some concepts about Fretwork

Fretwork is an interlaced decorative design that is either carved in low relief on a solid background, or cut out with a fretsaw, coping saw, jigsaw or scroll saw. Most patterns in this field are geometric in design. The materials most commonly used are wood and metal. Fretwork is used to adorn furniture and musical instruments. The term is also used for tracery on glazed windows and doors. It is also used to adorn/decorate architecture, where specific elements of decor are named according to their use such as eave bracket, gable fretwork or baluster fretwork, which may be of of metal, especially cast iron or aluminum.

To make it simple, fretwork is the “inside cuts” in the design, mostly in wood, but can be done on anything that can be cut



1, Fretwork through in 3000 years

The art of fretwork began more than 3000 years ago with fretted inlays on furniture in Egypt.  It has been popular in North America and Europe from the mid 1800’s until today.  Fretwork of the 1800’s and early 1900’s was done with hand fretsaws or foot-powered scroll saws.  In the 1920’s several scroll saws were designed for use with electric motors. 

The evolution of the scrollsaw is linked to the rise in popularity of fretwork (the sawing of intricate shapes from wood). Although there are examples of fretwork-like decorations on early Egyptian, Greek, and Roman furniture, these were probably carved or cut with a knife. It wasn’t possible to saw delicate wooden shapes until the late 1500’s, when a German craftsman (possibly a clock maker) devised a method for making fine, narrow blades.

In 1974 Helmut Abel of Germany started building the Hegner line of scroll saws which started a new popularization of fretwork as a hobby.

Fretwork was introduced to America in the mid-1800’s as Sorrento wood carving , so named because of the area in Italy that it was most popular. By the 1860’s, the first mechanical fret saws – called scroll saws – began to appear in the U.S. And so a great art form and hobby were born. Today there are over fifty models of scrollsaws available with many options.


2, Pattern of fretwork- The essential part:

Fretwork was a very popular hobby at the turn of the XX century, in fact those were the golden days of the hobby, patterns were produced and sold in great numbers and quality, not only in Italy, but in many western countries. “We always have the whole collection of patterns available, because the patterns are constantly reprinted. Many of these designs have reached 65 editions in a short time (65,000 copies). The number of patterns sold  until December 1905 is 5,932,400” said Pietro Barelli, an Italian businessman. Besides him, there are many other fans of this hobby who had a great deal of pattern. For instance, in October 1895, Hobbies issued its first number of weekly Hobbies magazine which contained an impressive collection of fretwork patterns, clocks, coffers, shelves and many other decorative items. At the beginning of the XX century, it sold many copies of the magazine, hundreds of thousand for sure, maybe millions. In addition, some people like Bowman, Russell, Wild were well-known scroll saw designer in the USA. In Italy, there were Amati, Ettore; in France there was Joubert-Tiersot,.etc.

Here is some samples of pattern


3, Process:

Firstly you obviously need wood, solid wood is ussually preferred but it’s a bit hard but it’s long lasting. Or you can use plywood (of which the edges are obviously less desirable thhan those of solid one, fine hardwood plywood such as teak, cherry, walnut, mahogany, maple…) or other modern materials.



The entire process of fretwork revolves around the technique of making inside cutouts of various designs. This is known as piercing work. First, you drill holes into the waste, or area that will be cut away; then you thread the blade through, reclamp and retension the blade in the saw, before proceeding to complete the cutout. Repeat this process as many times as necessary to finish the project.


Fretwork patterns originally were ornamental designs used to decorate objects with a grid or a lattice. Designs have developed from the rectangular wave Greek fret to intricate intertwined patterns. A common misconception is that fretwork must be done with a fretsaw. However, a fretwork pattern is considered a fretwork whether or not it was cut out with a fretsaw.


4, Fretwork by machine:


Computer numerical control (CNC) has brought about change in the method of timber fretwork manufacture. Lasers or router/milling cutting implements can now fashion timber and various other materials into flat and even 3D decorative items.

Washi paper-Great material for pop up cards and craft.


If you are looking for a material that looks traditional but still luxury with a variety of vivid color to add into your pop up cards, why don’t you take a look at Washi paper, a Japanese traditional paper that feels like cotton. Many origami player knows this type, but in fact, it can be used in other ways.

Washi is generally tougher than ordinary paper made from wood pulp, and is used in many traditional arts. Origami, Shodo, and Ukiyo-ewere all produced using washi. Washi was also used to make various everyday goods like clothes, household goods, and toys as well as vestments and ritual objects for Shinto priests and statues of Buddha. It was even used to make wreaths that were given to winners in the1998 Winter Paralympics. Several kinds of washi, referred to collectively as Japanese tissue, are used in the conservation and mending of books.

1, Origin


Washi (和紙) is a style of paper that was first made in Japan. Washi is commonly made using fibers from the bark of the gampi tree, themitsumata shrub (Edgeworthia chrysantha), or the paper mulberry, but also can be made using bamboo, hemp, rice, and wheat. The word “washi” comes from wa ‘Japanese’ and shi ‘paper’, and the term is used to describe paper made by hand in the traditional manner. Washi is one of the UNESCO’s Intangible cultural heritage objects.

2, Production process

Washi is produced in a way similar to that of ordinary paper, but fewer chemicals are used. It involves a long and intricate process that is often undertaken in the cold weather of winter, as pure, cold running water is essential to the production of washi. Cold inhibits bacteria, preventing the decomposition of the fibers. Cold also makes the fibers contract, producing a crisp feel to the paper. It is traditionally the winter work of farmers, a task that supplemented a farmer’s income.

Kozo is the most commonly used fiber in making Japanese paper. The kozo branches are boiled and stripped of their outer bark, and then dried. The fibers are then boiled withlye to remove the starch, fat and tannin, and then placed in running water to remove the lye. The fibers are then bleached (either with chemicals or naturally, by placing it in a protected area of a stream) and any remaining impurities in the fibers are picked out by hand. The kozo is laid on a rock or board and beaten.

Wet balls of pulp are mixed in a vat with water (and, in some cases, neri, which is a mucilaginous material made from the roots of the tororo plant) and one of two traditional methods of paper making (nagashi-zuki or tame-zuki) is employed. In both methods, pulp is scooped onto a screen and shaken to spread the fibers evenly. Nagashi-zuki (which uses neri in the vat) produces a thinner paper, while tame-zuki (which does not use neri) produces a thicker paper.


3, Characteristic


Warmth. Literally warmer to the touch than Western papers made of woodpulp, washi feels soft and creates a feeling of warmth in the viewer. Its tactile qualities make it wonderful for invitations and books.

Body. Since the fibres are left long and pounded and stretched rather than chopped, washi has a deceptive strength. Pure-fibred washi can even be sewn and was used for armour and kimono-lining in earlier times.

Strength. The length of the fibres and the nature of the raw materials ensure that washi is highly workable when wet. Thus it is excellent for papier maché, and etching in which the paper must be soaked. These long fibres produce a luxurious deckle edge, the rough edge which marks a handmade paper.

Soft translucency. Kozo and mitsumata are naturally translucent fibres, a quality specific to paper from the East. As such, it is used regularly for the transmission of light.

Absorbency. The nature of the fibres creates a ready absorption of inks and dyes. Papers that are “pure fibred” and dyed will result in much denser and more vibrant colour when fabric or watercolour dyes are applied.

Flexibility. Since the fibres position themselves at random, there is no real grain to washi. This gives the paper a resistance to creasing, wrinkling and tearing – and means it can be used more like cloth, for covering books, or boxes etc.

Lightness. Washi weighs much less than other papers of equal thickness. As a paper for books, it can create texts of apparent weightlessness.

Low acidity. Traditionally-made Japanese papers are truly acid-free if they are unbleached and unsized. Examples of printed papers exist in perfect condition in Japan from 1000 years ago. Today, papers from the village of Kurotani are among the finest archival papers.

Decoration. For centuries, colourful designs applied by woodblock or handcut stencils have created vividly characteristic papers, for decorative use. Recently, silkscreened chiyogami (small repeated-patterned paper) is available in an unbelievable range and widely used by craftspeople. Although made by machine, the quality available is about 70% kozo and comes in hundreds of patterns.

These features bring washi advantage in decoration, especially in superfluity product where colorfulness is necessary.


4, Application/Usage

Until the early 20th century, the Japanese used washi in applications where wood pulp paper or other materials are currently used. This is partly because washi was cheaper, but also because the unique characteristics of washi made it a better material. The different uses of washi are too numerous to mention, but include the following:

  • Ikebana — the art of flower arrangement, also known as kadō


  • Katazome — a method of dyeing fabrics using a resist paste


  • Kitemaking
  • Origami — the art of paper folding


  • Printmaking


  • Sculpture
  • Sewing
  • Shibori — several methods of dyeing cloth with a pattern
  • Shodo — the art of calligraphy
  • Sumi-e — the art of Ink wash painting
  • Sumingashi — a form of paper marbling
  • Ukiyo-e — a genre of woodblock prints
  • Washi eggs — covering eggs with washi paper
  • Chigirie  – using Washi for “painting” pictures
  • More than that, pop-up cards which is usually monotone, can make use of this traditional paper to bring an abundance of color and material, make pop up cards more vivid and close to real life

Which paper should be used in pop-up cards making?

I, Some concepts about paper in general


Paper is a thin material produced by pressing together moist fibers, typically cellulose pulp derived from wood, rags or grasses, and drying them into flexible sheets. It is a very versatile material with many uses; whilst the most common one is for writing and printing upon, it is also widely used as a packaging material; in many cleaning products; in a number of industrial and construction processes, and even as a food ingredient – particularly in Asian cultures.

It and the pulp papermaking process is said to have been developed in China during the early 2nd century AD, possibly as early as the year 105 A.D., by the Han court eunuch Cai Lun, although the earliest archaeological fragments of paper derive from the 2nd century BC in China. The modern pulp and paper industry is global, with China leading its production and the United States right behind it.

Besides category by purpose; basically, paper is classified by name and weight:

Name: there are several kinds of common paper and specific paper which will be shown latter in this thread.

Weight: Is the weight of paper calculated by gram per square meter (g/m2). In Europe, and other regions using the ISO 216 paper sizing system, the weight is expressed in grams per square meter (g/m2 or usually just g) of the paper. In the United States, the weight assigned to a paper is the weight of a ream, 500 sheets, of varying “basic sizes”, before the paper is cut into the size it is sold to end customers.

Paper weight is usually variant from 80-300 gram depends on types of paper. Printing paper is generally between 60 g and 120 g. Anything heavier than 160 g is considered cards. The weight of a ream therefore depends on the dimensions of the paper and its thickness.

Normal paper used in photocopying or printing is usually 70-80 gsm.

The thickness of paper is often measured by caliper, which is typically given in thousandths of an inch in the United States and in thousandths of a mm in the rest of the world. Paper may be between 0.07 millimeters (0.0028 in) and 0.18 millimeters (0.0071 in) thick.

All size in the Series A, B and C are rectangle shape with the ratio of 2 sides is the square root of 2, approximately 1.414. The area of A0 paper is 1m².

– The 2 sides of A0 are therefore determined as 841 × 1189mm

– The size of the blocks are in the order determined backward, smaller size has an area equal to 50% of previous size (divided by cutting along the line parallel to the short side).


II, Some common types/brand of paper (typically for pop-up cards making):

Various in weight and texture, paper is divided into several types, suitable for different kinds of pop-up cards:

1, Plain and thin paper (60-90gsm): Ford paper


This type is very popular and mainly used to print the template/ pattern, or only to draw. However, pop-up cards with many details can use this one to make the process easier.

2, Plain but thicker (120-180gsm or heavier):

A, This type can be found easily in any stationery shop anywhere. Typically Kishu paper is most common with a huge range of vivid color and weight. Kishu paper can be bought in Korea or Japan. Due to the variety, this one is useful in almost types of pop up cards


B, Canson also has plain paper products. This type is thicker and can keep the form very well. Thus this is usually used in cards making, no matter the price is a bit expensive. The surface of Canson is also suitable for drawing, sketching, therefore many artists choose this brand. Canson paper sometimes has veins which makes pop-up products look more luxury.


3, Texture paper

A, Conqueror Paper, of which origin in London, England, is another popular brand. Characterized by veins along the paper, this type is good at form-keeping. Being thicker and having deeper color, it’s best fit the cover of a cards. Whilst, some light colors of this brand like cream color is a good choice when cardss made by white paper is becoming uninteresting. However, sometimes vein is the problem due to the fact that they makes your cut not precise.


B, Thai Basil paper is also a special paper with vein along but thicker and heavier. The color is limited and mostly deep but when you need a thick paper to keep the form in 90 degree cards, it is still a good choice.
