Lay a damp towel on counter; place prepared pan on towel (to prevent slipping). Unwrap one portion of dough. Using a very lightly floured rolling pin, roll out dough directly on baking sheet to a 15x10-1/2-in. rectangle about 1/4 in. thick. Position patterns at least 1/2 in. apart on dough as shown. Cut around patterns with a sharp knife or pizza cutter; remove patterns.
