Aren’t these cute? I made them!
Just drill a small hole into the corks (don’t go all the way through). Cut some lengths of cording and wrap some transparent tape around the ends to keep it from fraying. Put a bit of hot glue inside the holes of the corks and insert the cord ends. They can be any color you like, with the cord as long or short as you like. Some of you may see these under the Christmas tree, so act surprised!
