You can decorate almost anything on large wall of the living room. How about mounting some nice paintings, some nice flowers and plants that come in artificial bouquet designs? They look fantastic, are not they? You can also mount at least one nice big sized mirror in the center to give a room an impression of big spaced if the area isn’t too spacious. The mirror reflects the things, also it creates an illusion of room inside the living room which makes it look bigger than in real it is.
