DIY Pilgrim Bonnet | Fold over one long edge of a piece of white crafts foam to create a 2-inch-wide brim. Staple it once on each side to hold it in place. Make seven evenly spaced 4-1/2-inch-long cuts on the long unfolded edge for a total of eight flaps.Punch a hole 1 inch from the edge at the center of each flap. Thread a 24-inch piece of white grosgrain ribbon down through the hole of the first flap. Pull the ribbon from each side to meet at the center.
