A brown paper bag can be used for sanding between coats. Blending of the accents will achieve the ultimate in decorator finishes. Accents can be applied using various methods. An inexpensive, stiff bristle brush will give you that beautiful "streaking effect". A simple household sponge works well for that popular "sponging effect". Loosely crumpled plastic wrap can be used for "mottling", applying accent and dabbing up excess finish. Wiping or dabbing with a rag or cheesecloth achieves a "ragging effect".
