Bake the cookies, but do not fill them. Seal them in an airtight container and freeze them for up to four months. Filled sandwich cookies may be frozen for up to two months; layer them between waxed paper in an airtight container.
It's easy to create an assortment of pretty cookies. Purchase a variety of decorative cookie stamps at a cookware store. Or flatten the dough balls with interesting kitchen finds; try a fork, a meat mallet, crinkle vegetable cutter or the bottom of a fancy cut-glass cup.
