Take the fringe
Measure the fringe around the ankle.
Cut off one end of the fringe
Add beads to the fringe using tweezers. Tip: use water to wet the ends of the fringe so it is easier to bead
Double or triple knot the ends so the beads don't come off
Attach the O-ring and one end of the toggle clasp to one end of the fringe.
Attach another O-ring and the other end of the clasp to the other end of the fringe.
It can even be a bracelet!
Finally, attach the fringe around the ankle of the sandal.
