Preheat oven to 350 F. Grease tart tins or cookie cutters. Arrange hard candies in bottom of tins or cookie cutters on greased cookie sheet. Place in oven for about 5 minutes. Watch carefully and remove when candy appears melted.
While still hot, twist pin or nail into candy to form a hole large enough for the gold string (keep twisting until candy sets). Place tins in freezer for 5 minutes, or until hard.
Pop candy out of tins or cookie cutters. When cool, thread gold string through hole to make into a hanging ornament. If desired, to permanently preserve (and not eat), cover ornament on all sides with clear fingernail polish. Colorful Christmas candy ornaments are ready to enjoy on your tree.
