Sorry for being a complete outsider but can someone explain why DIY bookbinding is interesting and/or useful?
1. A plastic separate "binder" like thing, which can be attached to the glued together side of the book. Since the textbook are glued together in factory, this additional binder makes the book more solid. 2. A plastic protect wrap to cover the book back/front covers. I used to hand-make these wraps from a very large paper as well, since it looks more "personalized" and cheaper.
I used thread and sewed it together. It was an easy project. It's like making a metal toolbox in high school metal shop. Sure, you can just go buy one, but it's nice to have one made by hand.
