Origami Basics 5

The Waterbomb base

There are several 'bases' commonly used in origami. These are a series of steps that lead up to an intermediate model. Many different models can then be formed from this base. The most commonly used bases were named by Samuel Randlett and Robert Harbin and these are; the Waterbomb base, the Preliminary base, the Fish base, the Bird base and the Frog base. We will start with the Waterbomb base.
The most commonly made model from the Waterbomb base is the Waterbomb. This is a simple origami cube. I rather like the final step which involves blowing into the small hole at the bottom and inflating the whole model. The Waterbomb can hold quite a fair bit of water, which can be poured into the hole, and is apparently quite aerodynamic...so I am told.

Crimp folds

A crimp fold is a form of pleating. It comprises of two reverse folds made at one. If you look at the beak on the penguin model, this can be folded with a crimp fold, rather than the pleat in step 6.
As well as practising to fold the penguin's beak by using a crimp fold, you can also try this simple chick model. The outside reverse fold in step 4 forms a nicely shaped bird head, and the crimp in step 7 forms the beak. This is a common method of shaping a bird's head.

Reverse folds

A reverse fold is where a tip is folded so that ends of the paper lie in between different layers, so that two or more layers are folded along a single crease. Now this sounds rather more complicated than it actually is!
There are two sorts of reverse fold. The most common is an inside reverse fold. Some paperfolders call this a hood-fold.

There are many uses for an inside reverse fold. To practice, here is a simple duck model. Three different sorts of reverse fold are used, one to make the tail, one to fold the chest and one to form the beak.

The other sort of reverse fold is the outside reverse fold. Here, the layers are unwrapped slightly. This has many uses, such as to form heads, feet, etc.
This next model uses one outside reverse fold to form the head. Notice that I have used a sheet of origami paper that is black on one side and white on the other. This produces a two-tone model. This use of origami paper makes models look very attractive. Some paperfolding experts can design models such as tigers and zebras where the stripes are a different colour to the rest of the model.

Origami Basics 2

Valley folds and Mountain folds.

These are the two simplest folds in origami. A valley fold means fold in front along the line. This is represented by a dashed line.
A mountain fold means fold behind along the line. This is represented by a dash-dot-dash line. Some books represent it as a dash-dot-dot-dash line.
Together, almost all folds in origami are combinations of these two folds, in one way or another. Some models are composed entirely of one mountain or valley fold at a time. These are called Pureland folds. These models are often the simplest types of model to fold, although some of them can be pretty complicated.
This is a simple model to start you off with. It is a simple Samurai helmet, part of the armour worn by a Japanese warrior. It is modelled here by a cuddly Tasmanian Devil. All the folds are valley and mountain folds. A 12" square of paper produces a hat 8" wide, which should be big enough for most heads.

Origami Basics 1

This section is intended for the beginner. It introduces all of the major folds in origami and shows how they are done. It also provides a large number of simple models that aim to allow one to practice these folds. By the time you have finished this section of my web site, you should be able to fold most of the models in the other sections. If you cannot complete a particular fold or section, please do not give up. Keep trying! It is unusual for someone to get an entire model correct at the first time. You will need plenty of practice to make perfect.


Paper and arrows

Most origami uses a single uncut square of paper, and this website is no exception. You can buy origami paper from most art shops and some origami websites. You can also cut a square from ordinary paper. 

There have been many ways in which origami instructions have been diagrammed in the past. About fifty years ago, an international system began to come into use. This is the Yoshizawa-Randlett-Harbin system, which is used in almost all modern origami books. I have a few Japanese paperfolding books and although I cannot read the language, I can understand the diagrams, because they use this international system.

On origami diagrams, arrows show you which direction the paper is to be folded in. It is important to understand which direction the arrow is telling you to fold. Shown here is a picture of all the arrows that you will see on this site and in most origami books. You will see how these are used on the next few pages.

Tools of the Trade

Origami is a pure artform in that it needs only one material a sheet of paper. So is that all that the aspiring paperfolder needs? Not quite; this page describes the tools that I most commonly use when crafting an Origami model.


Paper

This is the most important thing to start with! However, there are many different types to use. This sort that I most commonly use is simple white 40 g/m sq. printer paper. This is very cheap to buy in large amounts and is useful for most models. The best thing about it is that it is disposable when designing a model, I will get through several draught models first. If I used commercial Origami paper for each one, this would be a very expensive artform.
Standard 40 g/m sq. paper comes in a variety of sizes and colours. A lot of my display models are folded from coloured A3 sized paper. This can be decorated, painted, wetfolded, and is fairly good to fold. Origami paper can be bought from various shops. This comes in packs of various sizes and is usually coloured one size, and white on the other. This is thinner than standard printer paper, and a little more durable. It is also better for ‘two-tone’ models in which both the coloured and the white size are used, for example, to create a zebra’s stripes.

Foil backing

For complex models such as insects, I prefer to use foil-backed paper. This can be bought in a few gift shops but is expensive and difficult to find. I usually make my own. To do this, I buy very thin tissue paper and kitchen foil. By carefully spraying both sides with an art/craft glue and positioning the tissue, I can create a ‘paper’ ideal for complex models. This is rather messy, hence the newspaper in the picture. As this is very thin and durable, models that would become too thick to fold out of normal paper become much more appealing. It also retains its shape well, and insect legs and antennae can be molded in a way that one couldn’t do with paper.

Cutting

Although Origami paper comes in squares, most other paper doesn’t. As a result, it has to be cut if the model requires a square to start from. Although a good pair of scissors is an absolute must, I prefer to use a blade and a steel ruler. This is much more accurate. Another tool is seen here this is a circular blade attached to a ruler designed for cutting straight edges to measure. Finally, a good cutting mat is a far more sensible surface to cut upon than the family diner table.

Other tools

Finally, a selection of other tools comes in handy. Paper glue is useful for display purposes. For example, most of my dinosaurs have small shapes of paper glued on for eyes. A variety of inks, brushes and pens are a staple tool of mine. Before folding a model, I will often decorate a square of paper in various ways drybrushing, inkwashing, painting, etc. In this way, standard coloured paper looks so much more appealing. Lastly, art/craft spray glue is handy for texturing, foil backing and so much more.

Types of Origami

Action origami

Origami not only covers still-life, there are also moving objects; Origami can move in clever ways. Action origami includes origami that flies, requires inflation to complete, or, when complete, uses the kinetic energy of a person's hands, applied at a certain region on the model, to move another flap or limb. Some argue that, strictly speaking, only the latter is really "recognized" as action origami. Action origami, first appearing with the traditional Japanese flapping bird, is quite common. One example is Robert Lang's instrumentalists; when the figures' heads are pulled away from their bodies, their hands will move, resembling the playing of music.


Modular origami

Chinese paper folding includes a style called 3D origami where large numbers of pieces are put together to make elaborate models. Sometimes paper money is used for the modules. This style originated from some Chinese refugees while they were detained in America and is also called Golden Venture folding from the ship they came on.Modular origami consists of putting a number of identical pieces together to form a complete model. Normally the individual pieces are simple but the final assembly may be tricky. Many of the modular origami models are decorative balls like kusudama, the technique differs though in that kusudama allows the pieces to be put together using thread or glue.

Wet-folding

Wet-folding is an origami technique for producing models with gentle curves rather than geometric straight folds and flat surfaces. The paper is dampened so it can be moulded easily, the final model keeps its shape when it dries. It can be used, for instance, to produce very natural looking animal models

Pureland origami

Pureland origami is origami with the restriction that only one fold may be done at a time, more complex folds like reverse folds are not allowed, and all folds have straightforward locations. It was developed by John Smith in the 1970s to help inexperienced folders or those with limited motor skills. Some designers also like the challenge of creating good models within the very strict constraints.

Origami Tessellations

This branch of origami is one that has grown in popularity recently, but has an extensive history. Tessellations refer to the tiling of the plane where a collection of 2 dimensional figures fill a plane with no gaps or overlaps. Origami tessellations are tessellations made from a flat material, most often paper, but it can be from anything that holds a crease. The history of costuming includes tessellations done in fabric that are recorded as far back as the Egyptian Tombs.
Fujimoto was an early Japanese origami master who published books that included origami tessellations and in the 1960s there was a great exploration of tessellations by Ron Resch. Chris Palmer is an artist who has extensively explored tessellations and has found ways to create detailed origami tessellations out of silk. Robert Lang and Alex Bateman are two designers who use computer programs to design origami tessellations. The first American book on origami tessellations was just published by Eric Gjerde and the field has been expanding rapidly. There are numerous origami tessellation artists including Chris Palmer (U.S.), Eric Gjerde (U.S.), Polly Verity (Scotland), Joel Cooper (U.S.), Christine Edison (U.S.), Ray Schamp (U.S.), Roberto Gretter (Italy), Goran Konjevod (U.S.),and Christiane Bettens (Switzerland) that are showing works that are both geometric and representational.

Kirigami

In a variant of Origami, Kirigami, it is allowed to make cuts in the paper being folded. In traditional Origami, there was no Kirigami. Kirigami first emerged as a version of Origami, and then after it emerged, in the 20th century CE it was named Kirigami, and the practice of Kirigami was distinguished and disambiguated from "pure Origami".
