I have been saving the soup cans to do something with. I'm torn between little lanterns (putting holes in it and painting it, then putting a candle in it). Or using them to hold tools, craft items, pens, brushes, etc. I could probably eventually do both. We like soup around these parts. :) My boyfriend did ask me recently, just how many cans I needed to save. ;)
Oh... almost forgot... HERE is the link on Etsy's forums. Lots of creative ideas!
