I made something else from that Japanese origami book. I photocopied some pages and a friend translated the instructions for me. (Thank you, Jamie.) I thought this would be a quick, fun little project: make a book cover with a nifty pocket in the back. It turned out to be quite hard. I had to think a whole bunch and spent a lot of time staring in bewilderment. But I got it!
