Design by Bev Galeskas. Our lightweight felt hat offers a choice of three sizes and two brim variations. Sizes available in Child, Adult Small, and Adult Large. The exact finished size is determined by the amount of felting and the form used for blocking. This can be a head form, bowl or ball. Choose one that is just slightly larger than recipient's head measurement. Made in a single strand of worsted weight, it is great for handpainted yarns.
