Cut a 4-foot piece of DragonThread and thread a size 12 needle. Begin with a Hubble Stitch bezel around the 25mm cabochon using 8/0 seed beads. Transition to 11/0 seed beads for the smaller 18mm cabochon, following the same Hubble Stitch technique. Connect the two cabochons with Potomac Pearls and additional seed beads. Add a second row of Hubble Stitch with 8/0 seed beads for added detail. Secure the cabochons in place by tightening the bezel with a series of 11/0 and 15/0 seed beads. Embellish the outer edge with 3mm Potomac Pearls for a decorative finish. Complete the pendant by creating a bail with seed beads, allowing it to be hung on a necklace.
