Certainly interesting, but insanely complicated. The directions were probably follow-able, but I was far to intimidated to even pick up a square of paper to try. I also was a little put off by the soft, highly textured paper- I understand that Engel likes that softer look, but I guess I prefer origami with hard creases. Who even knew I had an opinion that strong about folded paper? Well worth a look, but the directions are for pros.
