crimp beads in different types of metals, even gold and silver.
Put your crimp bead around the knot you've tied between the clasp and the beads of your jewelry.
Start closing your crimp bead. Take your crimping pliers, and put your bead into the largest circle on your pliers.
Put low pressure on your crimp bead to start to close it. Turn the
crimp bead so that you press it gently from many different directions.
This will keep you from distorting the bead's shape.
Finish closing the crimp bead. Place your crimp bead into the smaller
circle of the crimping pliers. Apply low pressure to gently close the
beads. Turn the crimp bead so that you apply pressure from many different
directions until it is completely closed.
Repeat steps 2 through 6 over the knot at the other end for your jewelry piece.
