On a lightly floured work surface or between two sheets of parchment paper, roll out one disc of dough at a time into a 5-mm (¼-inch) thick sheet. With a 6-cm (2 ¼-inch) round cookie cutter (or other), cut cookies, reusing scraps. Place on the baking sheet, spacing them evenly. Bake one sheet at a time for about 12 minutes or until edges of cookies are lightly browned. Let cool completely on the baking sheet. Decorate.
