I’ve collected quite a lot of wine corks, with vague notions of getting crafty with them one day. My need for a better necklace holder was just the incentive I needed to upcycle a bunch. This was very simple: all you need are wine corks, a piece of cardboard, a glue gun, small nails, and a sawtooth hanger.
Cut a piece of cardboard from a cereal box, about 1-inch wide. Use glue gun to evenly apply glue to the back of a wine cork and place it on the cardboard to stick. Then glue a small amount to the side of the wine cork before applying the next, so the wine corks are glued to the cardboard and to each other. Continue until the cardboard strip is filled. When glue has solidified, gently push in a small nail into each wine cork. On the back of the cardboard strip, attach the wall hanger in the center. I applied my corks a bit unevenly so each side curves down a bit, but you could also make it straight. Voila.
