Mix dry ingredients with water to form smooth, stiff dough. Divide dough into three or four portions. Place each section between two sheets of waxed paper, and roll to 1/4-3/8 inch thickness. Use cookie cutters to cut Christmas shapes out of dough. While dough is still soft, use a straw to make a hole near the top of each shape where ribbon can later be inserted for hanging. Bake cut shapes at 350 degrees 15-20 minutes to dry. If desired, insert ribbon in hole, tie, and hang as ornaments.
