Spruce up your holiday cookies by sprinkling them with bold geometric patterns. No one will suspect that they get their artistic designs from a potato masher, a spatula, or some other kitchen utensil. Roll out and cut sugar-cookie or gingerbread dough to desired shape. Use any utensil with a cutout pattern. Dust with flour, place on top of dough, and sprinkle colored sanding sugar over the surface. Carefully lift away utensil. Or press dough with a lightly floured meat tenderizer; sprinkle indentations with sugar. Brush off excess.
