sorry!  some flat squares 10x10cm and15x15cm but I am unsure how thick the copper should be!  any advice would be greatly appreciated

Hi Anne

I am using for larger square copper plates 1 mm thick metal. Even for the bent shapes I use this material. For the very fine structured and shaped "wall jewels" I use 0.6 mm thickness. Hope, this helps.
