Start with an inexpensive, rectangular-shaped, wooden cutting board. You’ll need a length of cotton rope from the craft store along with hot glue and a metal ring to hang the shelf from a hook or nail in the wall.
You might opt to embellish the board by gluing decorative buttons to the corners. Hot-glue the rope to the underside of the board, and bring it up to suspend the shelf from the four corners. Loop the rope through a metal ring, and join the ends with masking tape. You can cover the masking tape with twine, raffia, or ribbon for a more finished look and added decorative interest. Use the shelf to display small, lightweight treasures.
