Jewelry is art, so why not frame it?
Step 1: Mark on the frame where you want the hooks to go.
Step 2: Use a drill to drill holes for the hooks, and then screw them in by hand.
Step 3: The hooks will stick out of the back of the frame, so paint wooden blocks (for top and bottom) and wooden strips (for the sides) and then glue them on to the back of the frame. This allows the frame to lie flat against the wall.
Step 4: Add hanging hardware to the the top block using the drill if necessary.
Step 5: Hang the frame and add your favorite necklaces!
