While traditional origami models are in the public domain the vast majority of published origami designs are of recent authorship and therefore cannot be published or used commercially without obtaining permission from their creators and or diagrammers. When you think of origami you automatically think of some complex paper structure that is difficult to fold but it doesn t have to be that way. Step by step diagrams are probably the most popular and easiest to follow way to show how to fold things out of paper.
