This class requires experience. It sure is helpful. To make a large hollow bead you must first know how to make a disk bead. Two disk beads actually. So the first day we concentrate on disk beads. The next day we make hollows. What's nice about a large hollow bead is that it weighs less for a biggie and it gives you a larger canvas to decorate. Love these beads! All supplies and tools are provided for this 2 days, 8 hour class. Just bring your desire to learn and your imagination. $350.
