Apply Design Adhesives from Clearsnap to the back of a glass ornament. I like these ones from Hobby Lobby because they are like a flattened glass ball, with a flatter surface on front and back but still rounded. A four pack was about $5.
Sprinkle the Design Adhesives with glitter. I used my favorite Clearsnap Glitter in Cinnamon Spice. If you do not have Design Adhesives, then rub-ons, vellum of clear stickers, and small diecut shapes will work just as well.
I then uncoiled one side of an S-shaped paper clip to make a hanger. A satin bow glued to the base of the metal cap finishes it all off.
