I cut 1 cork into 6 equal pieces using a knife on a cutting board.
Take 1 jump ring for each cork piece and place around the top and clamp down through the cork to hold in place.
Take 1 more jump ring and place into the jump ring in the cork. Place on wine charm hoop (or create your own hoop with wire). Add a charm if preferred. Repeat for the rest of the pieces of cork.
