What you need:
One pack small clear faceted beads, approximately 1/4" in diameter.
Two packs of larger clear faceted sort of flat beads.
Thread the beads directly onto the stretchy cord. Alternating the smaller round beads between the larger ones. After they are strung and tie off the stretchy cord. Stretch it out to isolate the knot otherwise the beads will glue to the knot. Add a couple of drops of super glue to the knot or it will un-knot itself. After it's dried, trim the ends of the stretchy cord.

It's lightweight and fun. Love!
