After printing, cut out the jack o'lantern carefully.
With small scissors, cut out the two eye areas. Make two small slits, where indicated by a " | " mark, on either side of the eyes. Thread about 1-1/2" of elastic cord through the front of one of the slits. Double this over the elastic at the back and staple the two thicknesses together. Leave enough elastic to go around your head, then thread the other end into the slit on the other side, double the elastic over and staple together as before.
