Feed thread through the thread hole in the hinged section of the bead tip. String one seed bead onto your thread then pass the thread back through the seed bead in the same direction, to hold seed bead in place. Pick up your bead tip and lay the seed bead inside the bead tip cup. Once bead is lying in bead tip, use a pair of flat-nose pliers and gently close the bead tip. Attached at the top of the bead tip is a loop you can open, use a pair of flat-nose pliers to twist the loop open and attach to your jumpring and/or clasp.
