A paint brush is described. The brush has a handle and a ferrule secured to the handle. The brush also includes a plurality of bristles having inner end portions received within the ferrule and outer end portions which project from the ferrule. A bristle setting material retains the bristles within the ferrule. A plurality of elongate spacer elements are arranged inside the ferrule generally parallel to the inner end portions of the bristles. The bristles and spacer elements are tightly packed in the ferrule and the spacer elements are distributed between the bristles so as to mechanically and positively space the bristles and provide a predetermined bristle density. Paint brush manufacturing methods are also described.
