If you don't have these exact beads or do not want to make the
Silver Metal Clay Heart Beads, this same design can be used with different beads. In fact, a charm of some kind would work fine as a substitute for the metal clay bead or even a small stone donut bead, and just about any kind of metal beads will work to substitute for the tube beads. You just need to make sure with those that the holes are large enough to accommodate the crochet chain you'll make; about 1mm in diameter will work.
