I need a couple of credit-card-size sheets of metal, either steel or aluminum is fine. I’d rather not spend $30 for a pair of wallet mirrors from Touch Of Ginger if I can avoid it, because these aren’t going to be used as mirrors.
Anyone have ideas where I can get sheet metal somewhere around that size? I can cut it down if need be, but if it’s already the size of a credit card that’s even better because it saves me some work.
