You'll need:
A few inches of wire
Round-nosed pliers
Chain-nosed pliers
Nylon-nosed pliers
The length and diameter of your wire will depend on what you plan to use the finished head pin for. Generally, I find that 21-gauge or 22-gauge wire tends to be good general purpose sizes for sterling silver or gold-filled wire. If you plan to use some extra heavy beads, you may want to bump it up to 20-gauge.
