1. Obtain the O-rings, plumber's chain, connectors, needle nose pliers and wire cutters from a large hardware store.
2. Look for a box with room for all the tools and supplies, with small compartments for beads and O-rings and some larger spaces for the wire cutters and chain so you can keep all your equipment together.
3. For example, a pattern of two O-rings, then one bead, in a set of three (six O-rings and three beads, one bead between each two rings).
4. Get ear wires, beads, wire cutters and compartment boxes at a jewelry supply, bead shop or crafts store.
5. For example, to make three pairs of earrings with a stack of six O-rings on each, you will need three small O-rings and six ear wires.
6. Add three plumber's chain connectors to use as catches for the necklaces (and wrist bands, if desired).
7. Hold the chain firmly and slip the last bead into the slot in the connector and tug down so it pops into place.
8. String the O-rings on the plumber's chain.
9. For three necklaces with 36 O-rings each, you'll need 108 larger O-rings.
10. Measure a length of plumber's chain for a necklace or O-ring choker.
11. Get enough plumber's chain for the three necklaces.
