Bead tips are usually used at the end of projects to attach onto clasps as shown in this picture.There are two types of common bead tips. One is a small metal cup with a metal hook to one side (below left).

The other is like a clam with two halves which is why it's sometimes called clam shells (above right). Another name is calotte. In both cases, there is a hole at the bottom where you can feed your thread or wire. I prefer the second type because it hides knots and crimp beads better.

This video tutorial by Blue Moon Beads shows us how to knot beading thread and hide them within the clam shells.

If you are using finer thread, knotting just the thread won't work. It will slip out of the hole. Find yourself a small seed bead that will fit inside the clam shell. Use the seed bead as a knotting anchor. Add a dab of glue for security. It's a great way to use up odd beads.

You can also use clam shells with beading wire and ordinary crimp beads. Remember to trim the wires before sliding the crimp beads within the clam shells.
