Trace around the inside of the cookie cutter on felt or heavy paper. Cut out. Coat the inside of the cookie cutter with petroleum jelly. Place it on a plastic plate also coated with petroleum jelly. Fit the cut out shape inside the cookie cutter pushed down to the bottom. In a disposable bowl, dilute white glue with an equal amount of water. Tear tissue paper into 1" squares. Dip each piece into the glue solution and crumple up into a tight ball. Tightly arrange crumpled pieces in a single layer at the bottom of the cookie cutter, pressing it flat with your finger tip. Microwave for one or two minutes on high. Let cool. Pop out of mold. Tissue paper is now permanently adhered to cut out shape. Let dry overnight. Tissue paper will be very hard. Glue pin onto back.
