Drive a nail through the inner rim of your paint cans, and the paint will drain back into the can. (I do this. It works.)
At first this looked really complicated, but the more I look at it, the more I think we could do this. The hardest part would probably be getting the nails in an outline of Tennessee, but we can trace it on the wood and go from there. Who's with me?!
Use clothespin to hammer nails in...Save your fingers!
