The Book - fold a piece of paper (rectangular or square) down the middle vertically making certain the opposite edges line up one on top of the other. For many origami figures you will need to add another book figure - open the paper and make another fold across the middle horizontally again, making sure the edges lie one on top of the other. Not all designs are combinations or parts of other bases; some like the box pleat are completely original. Some origamists saw the base as a set of areas each independent of the other differing only in their length and arrangement. With this in mind they went on to develop computer programs that are capable of doing all the math necessary to generate crease patterns for any base from a given length and area arrangement. In the 50's and 60's a group comprised of creators and folders established and international origami group to promote the popularity of origami. This group went on to form local as well as national organizations and also published the models of American, Japanese and European designers.
