Cut of the chain so it matches the ankle (incl. the lock). Mount a oval ring in both sides and a lock in one of them.
Put beads on pins, trim them and twist an open eye. Mark the middle of the chain and mount the pins 5 links to each side by closing the eye. Fill out the chain.
Put a crimp tube on a wire, that is pulled through the middle link and back through the crimp tube. Pull the bead all the way up to the chain and press it flat.
Put on rocaille beads in a suitable length.
Put the chain on the ankle and the ring on the toe and adjust the length of the chain. Put on crimp beads, pull the wire through the two middle rings, back through the bead, tighten, press flat and cut off.
Put beads on 4 pins just like in step 2, and mount the in the eyes of the rings.
