Chien gave me an origami book last Christmas. Thought it was going to be one that even kids can follow simply and thought of going through it with my nephew. NOT! It was so intense! The most intense folding, creasing, unfolding, uncreasing, for 2 hours! Anyone interested in testing their origami skills to the max? You can borrow the book from me. Paper not included. Get your own. Heh.
