Magnetic Shard Adornment

Something new! I got this idea the night before the craft fair and made one to wear:

 It's a pin, but not really, because it's a small collage with a shard face that attaches to a jacket or sweater with a very strong magnet meant for name tags. I got so many comments on it (and offers to buy it) that I decided to make a few more. Check them out - I think I'll make some for Etsy or my own webpage and sell them for $22 or so. Apparently, wearing the one I have is the best advertising! Thoughts? Comments? Suggestions?
