Measure out four sections of chain that are 5 inches each.
Cut 3 strips of 4-inch wire. (the beaded sections should measure about 2 ½ inches when done, extra is just for working space)
Thread the wire through the end of one section of the chain. Create a loop and thread a crimp bead through the wire on both ends of the loop. Use pliers to crimp the bead. Use the bead cover to hide the crimp bead.
String the bead alternating in gold and opal, increasing the size of the gold beads until the largest is reaches and then decreasing the size of the gold beads.
Thread a crimp bead and another end of a new chain section onto the wire. Wrap wire into a loop around the chain and through the crimp bead and any extra beads as possible. Crimp the crimp bead and use a bead cover to hide the crimp bead. Trim any excess wire.
Repeat the last three steps alternating the chain and bead sections until the necklace is chain, bead, chain, bead, chain, bead, chain.
Add clasps to the end of each side of the chain.
