Jewelry-making Techniques demonstrates how to finish your jewelry with crimps and covers. To use crimps and covers to finish your jewelry you will need 2mm crimps, 3mm crimp covers, crimping pliers, a clasp and beading wire. First, attach the clasp by stringing the crimp bead and one part of the clasp onto the wire. Take the end of the wire and string it back through the crimp bead to make a loop. Adjust the crimp bead up to the clasp and use the crimping pliers to crimp the bead. Repeat on the other end of the wire. Next, place the crimp cover over the crimp bead and close it shut with the crimping pliers. Repeat on the other end of the wire to finish off your jewelry.
