Peel the backing off the exposed side of the strips. Press the cork board into the panel of the shelf and hold it tightly for 60 seconds.
Pull the cork board away from the strips carefully and allow the adhesive to set for 1 hour. Replace the cork board, pressing each corner to secure the strips.
Place a picture hook along the frame of the cork board, making sure the hanging loop extends above the frame.
Hammer a round-head nail through each hole and into the frame.
Hold the cork board up to the shelf and mark a spot for each mounting hook. Screw the hooks into the marked spots and hang the cork board from the hooks.
