ACLPatternsandMore has a cool beaded zipper bracelet tutorial (shown above) which is a must see. The trick is the use of precision spacer beads in platinum colour to simulate the zipper teeth. These beads are uniformly flat with useful dual holes. You can get these beads from ACLPatternsandMore . They come in different colours!
They also have a couple of other cuff bracelet tutorials for that sleek look!
