When you have reached your final row, weave so that the thread is exiting the outside hole of the last Tila bead.
Pick up 1 size 15 seed bead, 1 Swarovski crystal, and 1 size 15 seed bead. Skip the last seed bead added, pass back through the Swarovski crystal and the other size 15 seed bead, and back into the Tila bead.
To get into position to add the next embellishment, stitch across the Tila bead and then through the outside hole of the next Tila bead.
