To form a curve: press belting with steam iron on medium low, pulling on upper edge while running over strip with iron. The wider curved edge rests at the bottom of hat crown. This is also called swirling the ribbon. For inner sweatband, pin wider curve of band into crown of hat, 1/8 inch from lower edge. Use stab stitch to attach. For outer band trim, again, place wider curve of band at lower edge of crown. Tack to hat at 2, 4, 8, and 10 o’clock (with center front being 12 o’clock).
