No matter what kind of beads, pendants, or discs you made, they must be finished with baking. This will set the clay so that the beads maintain the shapes and designs you’ve created. Always preheat your oven before baking, and follow the manufacturer’s instructions regarding baking times and temperatures. To bake your beads, you can:  Arrange them on a parchment-lined baking sheet. Place the beads on a length of firm, straight wire. Then, suspend the wire from an oven-safe baking dish and bake the beads like that.  Once your baking time is up, remove the beads from the oven and allow them to cool completely before handling them. In case you chose not to poke holes in your beads before baking, now’s the time to create the holes. Work with each bead individually. Hold a bead steady on a hard surface with your thumb and forefinger. With your other hand, use the drill to carefully drill a hole through the center of the bead.

Summary:
Bake them. Drill holes.
