Here's a quick and simple DIY project to add to your arm party swag --
large metal chain
jewelry clasp and jump ring
Measure each chain to the length of your wrist, mine is about 5.5" long. Line the two chains up and start "sewing" together the two chains with the embroidery thread. Tie a knot on each end and connect the two ends with a jewelry clasp and jump ring. Now you've got some added bling to your arm.
