I think this necklace would be perfect for belly dancing. You could make alter this to make it in to a belly dancing belt or even headpiece.
For this necklace you'll need metal hoops in various sizes and some small silver coins - the type you get in belly dancing stores.
Take one of your largest hoops and a coin. Open the coin's jump ring.
Slip the hoop between the jump ring and close.
Repeat this for a second coin. The coins have two sides, so you can arrange them with heads and tails, if you want a more varied look.
Slip a connector on to one of the hoops.
Use jewellery pliers to close the connector on the hoop side.
Slip the connector on to the second hoop and close.
Now take another connector and one each of the two smaller sized hoops.
Place the medium hoop inside the larger one and slip the top of the connector around both. Close the top of the connector with pliers.
Attach the smaller hoop to the bottom of the connector, inside the two larger hoops.
Close the bottom of the connector.
Repeat these steps, making your necklace as many hoops wide as you like.
When your happy with the width of your necklace, attach a connector through one of the end hoops and then attach to a length of silver necklace chain.
Repeat at the other side and you're all done!
