Heat oven to 350°F. On lightly floured surface, roll out 1/4 of dough at a time into 12-inch rope. Cut rope into 12 equal pieces. Roll each piece into 6-inch rope; shape each into wreath, overlapping 1/2 inch from ends. Place 1 inch apart on ungreased cookie sheets. Brush with egg white; decorate each wreath with 1 red cherry piece and 2 or 3 green cherry pieces.
