I made earrings using rounds from a wine cork. First step was to cut rounds from an old wine cork then I decoupaged scrap paper to the cork. Once the modge podge was dry I then added 2-3 coats of wood varnish. Final step was to screw in eyelets then add them to earring hooks from a pair of thrift store earrings.
