craftgrrl | Craft books you actually use.

I must have 12 or 15 books about crafts but the only ones I feel I actually got something out of are New Decoupage by Durwin Rice, and Stitch-n-Bitch. I refer to these books often. The rest of the lot are nice to look at for inspiration, and I have done a project or two out of them, but for the most part, I wish I hadn't wasted my money on them.

So, can anyone suggest any really good craft books? I am primarily interested in papercrafting of all kinds, but am looking for a good basic book about beadwork as well. Really I would love to hear about anything you actually found useful--for whatever craft.
