I loved this idea of a desk made from an old door with added legs. It makes for a wide, flat area which is something I need. Also they took a parson's chair and slipcovered it for a comfortable desk seat.Here they've used slatted display walls like you see in many stores. Painted it. Added shelves and pin-up boards etc. Especially clever is the hanging file system. Simple and seviceable!
Here an old metal tray has been painted to create a magnetic board. I've also found a metal cookie sheet works well. Depending on what you need to attach, mesh stretched over a baking sheet works well to display or hold earrings, necklaces or anything small enough to be held by pins. Let your imagination roam.
