Preheat oven to 350 degrees. Grease 4 cookie sheets. Divide dough into quarters. Between 2 sheets of wax paper, roll one quarter 1/8 inch thick, keeping remaining dough refrigerated. Cut with floured 4 inch round cutter. Bake 8 to 9 minutes, until edges are golden. Cool on wire racks. Repeat with remaining dough. Decorate as desired.
