Cut out a paper circle for the spider's face. Decorate it with a mouth and two eyes. (Note: You can draw the eyes or glue on wiggly eyes.) Glue the face to the front of the headband.
Cut out eight strips of paper (about one inch by eight inches each) to make the spider's legs. Fold each strip back and forth, accordion-style. Glue four legs to each side of the headband.
