Insert pegboard into a frame, and secure with metal frame clips. Thread thin elastic through holes, pull tightly, and knot in back to contain loose papers. To mount a box, drill holes in bottom, aligning with those in the board; attach to board with screws and nuts. For more stability, instead of picture wire, use two security hangers (available at frame shops).
