craft ideas using recycled materials

Does anyone have any fun crafting ideas using recycled materials?

My girlfriend posted this blog today of some lingerie she crafted last night. http://craftingagreenworld.com/2008/05/16/diy-easy-eco-lingerie/ I think they are totally fun and hot and was wondering if anyone else had any fun ideas to share.

Well, this isn’t lingerie or anything, but it is recycled! Use broken crayons and decorate jars with them. Here’s the link for how to do it.
