This is a FOSSHAPE(R) brim has a 1 inch back and 2 inche front and sides. The brim number in my collection is 311.and it fits a small to medium head size. This little brim added to any crown makes it a very sassy hat. This one piece FOSSHAPE (R) brim is hand blocked, unfinished and is intended for use by persons in the hatmaking business and those wishing to learn the art of hat making. FOSSHAPE(R) hat frames can be painted, colored and sprayed without changing the shape. These hat frames can also be covered with fabric or other pliable material and is part of a line of other FOSSHAPE hat frames created by myself Kay Durden offered through Kay's Art of Millinery.
