On floured surface, divide remaining half of dough into 2 portions. Roll each portion into 9x6-inch rectangle. Cut each rectangle into 4 whole triangles and 2 half triangles (see diagram). Press 2 half triangles together to form fifth whole triangle. Cut 1/2-inch strip from top edge of each dough circle on cookie sheet; set aside. Place triangle over each cut edge of circle, covering 1/4 inch of cut edge; press to seal, aligning edge of triangle with edge of circle. Slightly bend point of "hat" if desired. Roll each 1/2-inch strip into 2 (1-inch) ropes; attach to either side of "hat" for brim.
