I had a small piece of perforated sheet metal left after making my first sheet metal box and had propped it against a wall in my workroom. A few days later one of my husband's classmates (ahem, Ben) broke the glass in a small RIBBA frame I had. Not wanting to waste a perfectly good frame, I brought it, too, to my workroom and leaned it against the left over sheet metal. Then, genius struck! Ok, maybe not genius. To be fair, I already had the image in my head of the perforated metal earring display my sister had pinned (which inspired the sheet metal box).
I decided to cut down a piece of the sheet metal to fit into the frame and then ditched the board backing. I pressed the metal into the frame and secured with the existing clips and ta-da! A small earring display for the (maybe) 10 pairs of earrings I own. Sit on a dresser or hang on the wall. Now you'll never forget what you have stashed in that cavern of a jewelry box.
