I've seen memory wire used for every type of jewelry and wine-glass charms, what else can you do with memory wire?
String an assortment of your favorite gemstone or glass beads onto several coils of ring-size memory wire. Make a tight loop on each end using round-nose pliers to secure the beads. Pull each end of the scarf or sash through the ring in opposite directions. The beaded ring will add decoration to your scarf and hold the material in place without tying into a knot.
