When I was a kid, my friends and I spent a lot of time making these paper fortune tellers. I even have a few good ones from back then in a drawer somewhere. When I'm sitting around, whether at home on the couch or in a meeting or class, I'm always fighting the urge to fidget. I need to be doing something at all times. Sometimes I still make these fortune tellers, or paper footballs, or the thing where you fold a dollar bill into a ring. While browsing around the Instructables website I found instructions for this cool tiny diamond-paged book. It looks complicated and has a ton of folds but the instructions are clear. The fun part is deciding how and what to draw on the little diamond-shaped pages. This book would be a great vehicle for a secret message. If you're still a student, surprise your neighbor by passing them this complicated note.
