You do your design then get a block made at an engravers. You can use gold ink or whatever colour you want. I would suggest linoprint ink.
Order the 2 for 54 cents and see what you get. Hopefully it is two sheets of wallets.
There is a slightly wider size you can get, it's more of a square shape than rectangle. Try your local office supplies - I can't think of the name right now but you'll know it if you see it :-)
