Head Pins are a very useful finding to transform a bead into a charm or pendant (something that hangs).

Make sure to consider the length you need whether you are doing a simple loop, or a wrap which requires a longer headpin.

The gauge is also important. It must be able to go through the bead hole and stiff to create a strong loop, or more malleable for a wrap. The higher the gauge (number), the thinner the wire. ie. 22g is thicker than 26g.
