Selling copper wire for crafts?

the gauge definitely depends on the craft. my wife wanted custom hangers with all her bridesmaids names in them that she found on (I believe it was) etsy. if I remember right they were 20 bucks a piece. she is very crafty, and I told her to go into my wire room and find that wire, strip it, bend it, and put it in a wood hanger for about a dollar. she went with 14awg solid for her craft, but yet I have had a lady who made these neat little bracelets with some kind of fake gems on them and she used copper from stranded 8awg wire.

not sure if I did it the way a store would or not but I sold it for 20 cents over my highest barebright price... I'm almost positive ebay and such sites would bring a higher profit margin.
