Thread bead onto head pin.

Measure approximately 3/8" from top of bead and cut the balance of the headpin off and use round nose pliers to bend it at a right angle away from the bead.

Grip the end of the wire at a position on the round nose pliers to create the size loop you prefer by rolling the pliers up and around.

Re-grip the loop to finish turning and closing

Note: Use the very top of your round nose pliers to create smaller loops.
