Tools and Materials:
Chain (mine was from the junk jewelry pile) or other trim
Needle and thread
How much chain and elastic you need depends on the size of your head. You want enough so that the chain comes to behind your ears, and when it's stretched, the elastic should fit over your head but still fit snugly at your nape.
Double up the chain, and sew each end to one end of the elastic. That's it!
These are so easy I made two! My sister's wearing one with silver ribbon.
