1) Take one headpin and thread one bicone onto it. Use your side cutters to cut off the excess wire and create a loop with your Chain Nose and Round Nose Pliers. Before completely closing the loop, attach to one of the filigrees.
2) Take one of the Lever back earrings and open the loop slightly with your Chain Nose Pliers. Remember to open to the side and not out. Attach to the other side of teh filigree. Close the loop.
6) Repeat steps to create the other earring.
