Recycled crafts

I am always looking at every item in the recycling bin in my home trying to figure out if I can make it in to anything. It drives my family nuts. I sometimes get great idea's from other peoples blogs. Today I figured out that a Pringles can lid would make a great serving tray for an American Girl Doll. When I get it made it will be a post. Any other great ideas? It will be seen I guess.
