if interest..email me... i will give you a copy this e-book
This e-book begins with simple models and works up to more intricate ones. Each is folded from an uncut square. The book also contains a brief explanation of the symbols used to indicate various folds, and several pages explaining folds and "bases" considered basic. (Many models share the same initial folds; the result of some common beginning folds is called a base, e.g. "bird base", "frog base".) Here are the critters you learn to fold. ("Steps" is really the number of illustrations, not the total number of folds, which would have been more tedious to count. It's still a reasonable indicator of complexity, though.) Angelfish (8 steps) Seal (18 steps) Walrus (21 steps) Starfish (29 steps) Crane (37 steps) ... not traditional. Swan (21 steps) Eagle (14 steps) Owl (23 steps) Tyrannosaurus (18 steps) Brontosaurus (16 steps) Snake (24 steps) Turtle (39 steps) Frog (49 steps) also Frog With Toes (+ 24 steps), for the tree frog look. Bear (39 steps) Kangaroo (40 steps) Giraffe (41 steps) Fox (56 steps) Elephant (55 steps) Antelope (51 steps) Spider (86 steps) Crab (86 steps) Lobster (114 steps) Ornament (21 steps) Star (19 steps) .
Special origami paper, often also referred to as "kami" (Japanese for paper), is sold in prepackaged squares of various sizes ranging from 2.5 cm to 25 cm or more. It is commonly colored on one side and white on the other; however, dual coloured and patterned versions exist and can be used effectively for color-changed models. Origami paper weighs slightly less than copy paper, making it suitable for a wider range of models.
Foil-backed paper, just as its name implies, is a sheet of thin foil glued to a sheet of thin paper. Related to this is tissue foil, which is made by gluing a thin piece of tissue paper to kitchen aluminium foil. A second piece of tissue can be glued onto the reverse side to produce a tissue/foil/tissue sandwich. Foil-backed paper is available commercially, but not tissue foil; it must be handmade. Both types of foil materials are suitable for complex models.
Washi (和紙, Washi?) is the predominant origami paper used in Japan. Washi is generally tougher than ordinary paper made from wood pulp, and is used in many traditional arts. Washi is commonly made using fibers from the bark of the gampi tree, the mitsumata shrub (Edgeworthia papyrifera), or the paper mulberry but also can be made using bamboo, hemp, rice, and wheat.
Artisan papers such as unryu, lokta, hanji, gampi, kozo, saa, and abaca have long fibres and are often extremely strong. As these papers are floppy to start with, they are often backcoated or resized with methylcellulose or wheat paste before folding. Also, these papers are extremely thin and compressible, allowing for thin, narrowed limbs as in the case of insect models.
Paper money from various countries are also popular to create origami with, called "Moneygami". It is common to create the figure depicted on the note itself.
