Hans <h...@papirfoldning.dk> was kind enough to mention my book Origami Alfresco in connection with this thread.
Although he is correct that >Dave Mitchell calls it ... sketching without pen or ink that idea came from the late Eric Kenneway who, I believe, called it 'drawing with paper' ... which is the term I would normally use. It seems to me that there is quite a difference between this technique ... creating recognisable (I hope!) pictures and the creation of bi-colour patterns and I don't think they ought to be conflated. I also don't think it matters whether the outline of a drawing with paper design is rectangular or irregular. I think most of Eric's designs were the latter. As Hans says many of mine are rectangular ... but that was because I conceived of them as sketches drawn in an artists notebook. As always I think that the choice of a regular or irregular shape is one that depends on simplicity and elegance. It would surely be foolish to ruin a good design just to arrive at a rectangular outline? For those who are interested I have a page on drawing with paper designs here ... http://origamiheaven.com/drawingwithpaper.htm Dave
