Thread onto the Tigertail or beading wire a silver or gold colour metal crimp bead, add a small bead and then take the end of the wire through the loop of your clasp and then thread back through the small bead and the crimp.
How to use a Crimp
Slide the crimp up towards your clasp and when in place flatten with a pair of chain nose pliers. Add some of your beads sliding over both pieces of wire and then trim back any excess wire with a pair of wire cutters.
