I would like to replace the four (4) glass plates in my pie safe with copper that I can put a pattern on for a different look. I can't seem to find the copper sheets in A.C. Moore or Michael's arts and crafts stores. Do you know where I can get this material? I would also like to know if you have any patterns we can tap out using a common house nail? I have seen only finished pie safes and such. Any help would be greatly appreciated.
