Bead tips are made for finishing necklaces that are made with thread or cord. To use them, bring your thread up through the hole, into the clamshell part. Tie a knot to keep the beadtip tight against your last bead. Add a drop of glue and pinch the clamshell closed. Add your clasp to the metal loop and close the loop. Bead tips can also be used with organza ribbon, providing the hole is large enough, and jewelry wire. When using a bead tip with jewelry wire, use a small crimp to hole the jewelry wire securely in the clamshell.
