Formula Cans

I have a TON of formula cans that I don't want to throw away because I'm waiting to come up with some ingenious idea for use. If anyone wants some they are welcome to them. I've heard they are good for storing baking ingredients like flour, brown sugar, etc. Also they could be good for storing little toys. Someone also suggested maybe storing yarn, poking a hole through the lid so that it doesn't get all messed up. If anyone wants some please let me know OR if you have other great ideas for their use, please tell me! :)
