Tài liệu tham khảo cách xếp giấy Nhật Bản origami | I I Preface ft In good origami the folding process itself is as important as the finished work. If the folding has been laborious exces sively complicated and wasteful all these faults will manifest themselves in origami that is stiff unattractive and messy. But if the folding is economical and rational the finished origami is certain to please. The economy and efficiency of the folding method become the characteristic traits of the folded figure and in this way give direct expression to the simple but expressive qualities of paper. To carry this line of thought slightly farther I can say that in devising new origami that can be folded with ease and economy a rational design route is essential. That is to say using just any old folding method in any number of haphazard combinations will never give effective attractive representa tion to the form you are attempting to create. The aim of this book is to enable you to take full advantage of the pleasure to be had from making beautiful origami. One aspect of this pleasure is the fact that you can fold paper figures anywhere and at any time. The works shown in this book require no special equipment scissors or glue. I hope that when you go on a trip or when you have a few minutes of spare time while you are waiting for someone or something you will slip this book and a few pieces of square paper in your pocket and use your leisure time to enjoy making origami. The first chapter is devoted to presenting a clear method for creating your own origami without time consuming effort. The book is small but I have tried to fill its pages with a maximum amount of helpful information. July 4 1973 I ft Kunihiko Kasahara Contents Preface 3 Symbols and Folding Techniques 6 1.
