@wffl since it is also a material that lends well to being stiffened, you could get a bigger brim out of it. Felt is pretty flexible, and not shiny of course, you can add texture kind of as you like, it can be stiff or more floppy, and is kind of classic hat material. Softer than leather, but you can get a decent brim especially if you add a stiffer material around the outer edge. The cheapy ones are usually like, those nylon Halloween costume ones. Those fall apart. Leather or felt 💪
