This is a frame I made for my son in a very quick project- only took 15 minutes in the software and about 12 minutes of carving time per side. The interior cork is just under 2' x 3', just the right size to hold a store-bought inexpensive bulletin board. The frame is only $4 worth of pine with golden oak stain and then polyurethane on it, but it jazzes up the board a lot...
