Origami paper comes in as many varieties as one can probably think of: white or colored, plain or patterned, textured or smooth, shiny or dull.

Here is a short introduction to the more common types of origami paper.

basic paper The most basic type of origami paper is colored on one side and plain white on the other side. It is often recommended that beginner origami folders practice on this type of paper as some of these one-sided papers can often be found easily and for a relatively low price.

duo paper Duo paper is paper with two colors on it, with one on each side of the sheet. This type of paper is very useful when folding a model that will end up showing both sides of the paper. That is not to say that it cannot be done with the basic one-sided paper. Sometimes, however, a design just looks better with two colors.

duo paper Foil paper is just that. This type of paper that one side that looks rather like aluminum foil and can be either textured or smooth. This type of paper is also much stiffer than regular paper, which may cause first-time users a bit of getting-used-to. Also, because creases that are made in foil paper are much more noticeable than on regular paper, the folder should try his or her hardest not to make any mistakes that could lead to unwanted crinkles that could potentially detract from the final look of the model.
The reverse side of foil paper is usually a plain white.

washi paper Washi and chiyogami are traditional Japanese types of paper. The word "washi" means "Japanese paper" and is generally made with fibers that give the paper more texture as well as make it softer than normal paper. Chiyogami is simply washi that has traditional Japanese designs and images printed on it.

Origami paper comes in all sizes and not always in the shape of a square, even, which is what most design are folded from. Some designs use rectangular pieces of paper. Others use circular pieces of paper. Some even require that the paper be cut in certain ways and shapes.
