Wearing one of these festive foam hats is a fun way for anyone to show off her St. Patrick's Day spirit.
First, mark and cut one sheet of foam (as shown). (Use wider circles for a larger hat.) See cutting instructions for a whole sheet.
Cut the second sheet of foam in half lengthwise and glue the 5- by 6-inch rectangle to the end of one half. Allow the glue to dry.
Roll the strip into a cylinder that fits inside the ring of foam (the hat brim), then glue the overlapped edges in place, using the tape or clothespins to hold them until the glue has dried.
Make ¾-inch vertical cuts (approximately 1½ inches apart) around the bottom of the cylinder, as shown, then fold the tabs outward. Fit the brim over the top of the cylinder, pulling it down to the bottom, and glue the tabs in place against the underside of the brim. Glue the 7-inch circle onto the top of the hat.
For the shamrock, glue one end of each pipe cleaner to the middle of a foam heart. Allow them to dry, then twist the pipe cleaners into a stem.
Make two small cuts in the front of the hat, one above the other, close to the brim. Poke the stem in through one hole and out the other, bending the end so it rests on the brim.
Finally, tie the ribbon around the hat, and it's ready to wear.
