I was browsing through the blogs yesterday (in addition to not posting, I also haven't been reading other blugs much either) and the Fabric Art Journals has a link to as site called instructables. It describes itself as "the world's biggest show and tell" and it is FULL of well illustrated (with photos) instructions (duh!) on everything imaginable and more - WARNING!! you could get stuck in that site for a looooooooong time.
The Envolope Book was the first post I looked at, and this one about making your own shrink plastic by recylcing is pretty interesting too (we used to do this with chip packets when we were kids - don't know if that still works?).
