Thread one or more beads onto it and form a loop. This loop can be simple or pigtailed, and will enable you to hang your assembly in your jewelry.
Use 3-in-1 pliers to form curls with nails. If you don't have any, opt for round-tipped pliers and cutting pliers.
When choosing a bead to crush, bear in mind that the wire will pass through the bead twice. You therefore need a bead with an internal diameter slightly larger than twice the diameter of your wire.
The crushable bead cover should be larger than the bead to be crushed. Approximately 1 or 2 mm larger. So for a 3 mm Crimp bead, choose a 4 mm bead cover.
