Intermediate level kit. Includes: instructions, magnetic clasp, faceted metal beads (quality Tierracast brass-oxide-plated lead-free pewter), seed beads, cord, and needles. (All materials except crystals). The magnets in the magnetic clasp are surprisingly strong, though for extra security you may wish to add a safety chain. Crystals sold separately. Add 39 Swarovski 4mm bicone crystals (not included, sold separately) to make a 7" bracelet. Choose your Swarovski 4mm bicone color and add to the cart. No other tools needed except scissors to cut cord. Previous beading experience recommended. Tennis Bracelet designed by Rayne Austin. Instructions reprinted with permission.
