Sheet Metal for the 2x2 metal booklet swap

If you can't find any old signs or something like that, then you can go to basiccopper.com to get some copper sheet. I used the 10 mil. You want it thick enough so it will hold up with other metal pieces on it. 16 mil is a little too thick and harder to cut. They sell scrap packs and smaller sheets. You can always contact them to ask specifically what you need for the swap. You might want to try the copper foil. It is fab!
