This idea is so great! All you need is some basic items: small hooks, old frame and metal mesh that you can purchase in the garden section of your local home improvement store. Instead of mesh you could also go for a thick (upholstery) type of fabric. The small hooks are attached to the bottom of the frame to allow necklaces to be able to hang. The metal mesh or fabric is attached with a staple gun to the back of the frame. To change this up paint the frame or stain it a different color or distress it. If you do not want the metal to show use a spray enamel and spray the mesh front and back before attaching to the frame.
