If you are DIY, it's not necessary to have those special clasps. You can just permanently attach your wiring from your frame to your center piece and then wrap with your decorative covering over any wire you select. Ensure that your wrapping material is reasonably heat-proof so you don't end up with melting or flammable materials.

I actually like the look. :)

@Kim Then you could probably find something like this at any place that sells jewelry-making supplies. If you are in the USA, try Michaels, JoAnn, or Hobby Lobby.

Sorry. My reply makes no sense. For some reason only the first coup,e lines of your response showed up but now I see it all. Thx. Good idea.
