This is what Jerri Reimann did with her charms:
Jerri wound copper wire around the handle of a paintbrush to make a long
coil. Then inserted some braided leather cord into the coil and
stretched the wire out a bit. I made a loop on both ends of the cord and bound
them with fine copper wire, then attached a hook made from more wire.
Finally Jerri arranged the charms in the order she wanted them and attached
each to the coil with jump rings.
