Here are a few basic tips, if you want to give it a go:
1. Wire comes in a variety of shapes, but round is most commonly used and easily available.
2. Try using copper, brass, or colored craft wire instead of the pricier sterling silver or gold wire.
3. If you are planning to coil or spiral the wire, you should use dead-soft wire, which is easier on the hands than half hard or full hard. And keep in mind that as you are working with the wire, it work-hardens itself.
4. Work-hardening stiffens and strengthens the wire and can be done with a rawhide mallet or ball-peen hammer on a steel bench block. I found that it really did strengthen the hook part of my clasp!
