Brainstorming: coin flips

I'm dying to do something with these coin flips, but nothing is coming to me.

A few years ago, I got together with some of my neighbors to have a Christmas-gift sale around Thanksgiving time. One neighbor set up her cosmetics line in my living room. Another set up her cooking-party line in my dining room. And the YaYas and I set up our arts in my studio. (I remember that Lisa Bylander made some gorgeous sets of notecards.) I put up my Christmas tree so we could display our handmade ornaments. Jann Bell, the queen of miniature painting, had made Christmas ornaments out of coin flips. Jann removed the mylar and replaced it with squares of vellum, and on the vellum she painted beautiful little motifs, accented with the tiniest rhinestones I ever saw. She dangled the little ornaments from pretty ribbons or cords, and they looked so beautiful on the tree with the twinkie lights shining through them. They sold like hotcakes, of course.

I don't want to steal Jann's idea outright. (I couldn't if I did want to--my painting skills are laughable next to Jann's.) But I'm thinking I could make Christmas ornaments to attach to the front of Christmas greeting cards--my annual twofer experiment for my B&M shops. Maybe I could trap something pretty between the layers of mylar? Or make tiny spiral Christmas-themed books with my new coil binder?

There must be a million things these coin flips are good for, but my brain just won't kick into gear. I'd love to see some brainstorming comments on here. Help me out!
