You will need:
1- A plastic gear (this one was scavenged from an old computer).
2- Copper jewelry wire.
3- Embellishment of your choice.
5- Needle nose pliers.
7- E-6000 glue
Take the gear and start wrapping the wire around the gear. When you get to the end of the wire tuck the wire in the back of the piece bending it downward so that it does not poke into the skin. You will need to use the pliers to wrap wire and to bend.
Once you are satisfied with how you have wrapped the wire glue the embellishment of your choice, (I chose a music note rose)
Run the chain through the back of the copper wiring to make it a necklace.
