After thinking about how to finish this piece, I decided to glue in onto a little 5"x 5" stretched canvas that I found at a buck store. (Gotta love those dollar stores for inexpensive crafting supplies). I just happened to have some matching red decorative trim in my stash and glued it around the border. I painted the sides of the canvas black. It doesn't look too bad against my red wall and a few sequins and beads give it a bit of sparkle.
I would like to do something similar on a larger scale and with a lot more detail.
