Cut a 3" (8cm) piece of 16-gauge copper wire and make a loop on one end. Patina the wire.Thread one of the metal disks onto the wire and then thread the wire through the tube and through the other disk. Coil the end of the wire to secure the disks to the bead.
Spiral the excess shafts of the U-shaped wire and fold it against the bead.
Patina the wire coil using liver of sulfur.
Thread the bead onto one end of the coil, making sure to pick up the beginning of the coil at every rotation.
When the bead has fully attached to the wire, curl the two wire ends around the coil to secure the bracelet, using chain-nose pliers to crimp.
