With this beard and top hat, your trick-or-treater will look like a born leader.
Hat: Abe's hat is felt over a posterboard base. Wrap an 11- by 14-inch piece of black poster board around your child's head to get a comfortable fit. Tape the seam of the cylinder with black tape. Cut a piece of black felt that will cover the cylinder.
For the brim, cut an 11-inch circle from poster board. Place the cylinder on the center of the circle and trace around it with a pencil. Draw a smaller circle about 1/2 inch in from the first, and cut it out. Cut 1/2-inch tabs into the inside of the ring, as shown. Make a matching ring from black felt; the interior opening should have the same diameter as the cylinder. Fold the tabs of the paper ring up, fit the paper cylinder inside the brim, and tape it in place.
Trace the top of the hat onto poster board and cut it out. Cut a matching circle from felt. Tape the paper circle to the top of the hat. Glue the felt pieces to the poster board hat.
