A 6-Coil piece of steel memory wire, in 3 sizes. Do not use jewelry wire cutters to cut this type of wire. The steel wire is too hard. If you have a memory wire specific cutter you are set. "OR" Go to the family tool box and use a large strong wire cutter. Before you start to bead, be sure to make a loop at the other end of the wire. The tip of the wire used to place the beads on is sharp so do not leave small children unattended when using memory wire.
