Several years ago I had bought a hanging wood curio cabinet on clearance. I removed the doors, sanded it, filled the holes where the doors were attached and painted it. It hangs above one of my aquariums and displays stones, sea shells, sand dollars, starfish and a hermit crab made by BewitchingDreams. I had saved the doors and glass thinking one day I might use them to create frames.
I filled the holes where the door hardware used to be. Sanded and painted the wood with primer then red paint and a coat of sealer. My kitchen is mostly red and white. Then I cut a piece of expanded wire mesh (you could do the same thing with chicken wire). I have this because I use it to reinforce concrete stepping stones and concrete sculptures. It is magnetic so I knew it would be perfect. I spray painted it with primer then after that dried, white spray paint. It is now hanging above my kitchenaid mixer using picture hanging hardware.
