Origami is an art of paper folding. You can fold sheets of paper into ships, animals, or flowers. It's a lot of fun, especially for children. I think, however, origami is more than model-making. In my opinion, origami is bringing out, through folding, the nature of paper which the pieces of paper concealed before folded. (For detailed discussion, refer to "Philosophy of Origami," which I have contributed to Origami Tanteidan web-site.)
The paper itself has some charm since it is made by someone with sincerity. So you should not spoil it when folding. Moreover, if you cannot make it more charming, there will be no sense in folding a sheet of paper. Origami resembles the cooking in this respect. As you should make the most of the nature of food in the cooking, you should make the most of the nature of paper in origami. And as the finest cuisine can be a moving fine art, origami can.
You can make highly complex models, such as a six-legged, four-winged, and five-horned beetle, by folding a sheet of square paper. But remember all the shapes are prepared in it. No one can elicit more than what the piece of paper embrace. Origami resembles the theater in this respect. Scriptwriters in the theater are equivalent to designers in origami, actors to sheets of paper, and directors to folders. While you make the paper into the shape you want, you should consider into what shape the paper wants to be.
