Interior ecoration or decor is the art of decorating a room so that it is attractive, easy to use, and functions well with the existing architecture. The goal of interior decoration is to provide a certain "feel" for the room; it encompasses applying wallpaper, wall decals, painting walls and other surfaces, choosing furniture and fittings, such as light fixtures, floorplans and providing other decorations for the area such as paintings, sculptures and carpets. In some cases, interior decorating is performed professionally by certified interior decorators (C.I.D.)
