Paint the fondant with red vegetable dye and spread it out. Cut a long and wide strip. Find the middle of the strip and fold the two ends to the center to form a bow. Glue the ends with water and place paper inside each hole of the bow. Let the bun harden before removing the paper. It is advisable to make the bow 2 days before. Cut two medium strips of the same width and cut the ends to form the ribbons of the bow.
