These are gorgeous and so versatile! They bend easily and have a hole at the top, so you can either use wire or thread to string them. I've been using these as long dangly earrings. They are very Art Nouveau looking when paired with right colors. I think, since they are so easily manipulated by bending, etc, they'd probably look interesting as a necklace focal point (maybe press flat?). This particular finish is a bit loud for my taste. It's very shiny and bright. I'd love to apply some patina finishes to them, tho. I saw a kit somewhere on Beadaholique that would be perfect for the job:)
