Here's another demo painting for which I painted a matching background. I like this presentation, especially when the top painting would lose something if a frame covered up 1/8th inch all the way around.
The top painting is covered with epoxy and features various textures, metal leaf, tacks, and metallic paints on 1/8 inch mdf board.
