Plain Crown Molding Unadorned Crown moldings are immensely popular with those looking to style their rooms in a traditional manor. Replicating many of the old style profiles, and providing some twist with newer profiles, you're sure to choose a molding that fits perfect with your décor. Typical uses are living rooms, family rooms, dens, game rooms, media rooms, hotels, grand halls, dining rooms, and decor for shelving or mantels.
