The frames I purchased from the Dollar Store. I removed the backing and glass, and used scrap cardboard covered with fabric for the board. The cardboard was just the right depth for the frame and the hooks. I had thought to use wood for the backing, but the hooks were plenty secure in the cardboard. I did spray paint the hooks black, which took a few coats.
The top frame is a canvas transfer I did using this technique. Such a fun technique! I really to play with that one more.
Total cost: approx. $11
