if you wanted to be really cool, you would buy a regular necklace that looks really cool. then just get an alligator clip, you can find them on anything, especially at electronics stores, then you can actually assemble a necklace to your design. i know i got one on my key ring that i made using some wire and the clip. it has come in handy more than i thought it would used it the first day i made it, and the day after and after, great for when something is rolled. i like the keys though cause the smell can get on the clip, and roach smell isnt always that awesome around the nose.
