Tubular and round crimp beads are most often used when stringing a bracelet or necklace which has been strung with wire. The crimp beads finish the end of the beaded piece of jewelry and help create a loop for the clasp to be attached to. Use these as a bead stop to prevent other beads from coming off your stringing material. To do this, slip it onto the end of the beading wire. Next, take the other end of the wire and loop it back through the crimp bead. Using crimping pliers, clamp down on the bead to squeeze the bead inward onto your stringing material.
