Cut other half of dough into 15 (1/4-inch) slices. On ungreased large cookie sheet, place 10 slices 2 inches apart for kids' heads. Cut remaining 5 slices in half crosswise to make collars and hats (see photo). For collars, cut half slice into 2 pieces and attach under head. For hats, shape half slice of dough with fingers into hat shape; do not attach at this point.
