I've used these for years in my own work, mainly bodacious composition pieces in the collage style. If you visit http://www.imageevent.com/bsue/design you will see numerous examples of pieces I made long ago using these pieces. We also have some YouTubes that show you how to do it. The necklace bases (or crescents as I call them) are also useful to emboss, dent, hammer, texturize and then ink or paint, wire, wrap with ribbon. If you'd like to learn more, check the roster of YouTube videos made by B'sue Boutiques.
