Summarize this article:

Rather than wallpapering the whole room, apply it to the sofa wall alone. The resulting background will reframe your seating area while adding a splash of color and texture. And, since it provides such a striking contrast, it can help break up the visual monotony of bigger rooms. Keep the design consistent with the palette you've picked out for the room, as well as its general energy. A coral and seafoam green chevron pattern will look out of place in a room with elegant Victorian decor, but will be right at home in one done up in colorful 1960s retro. Even if there's nothing behind it, it will add an air of chic mystery. A simple wood slat screen should be versatile enough for most homes, or you could go with an elaborately painted Chinese style to suit other exotic accessories. Be sure to unfold the screen so it will fit neatly behind the couch, unless you prefer to keep your seating pulled in closer to the center of the room. Update an uninspired screen with a fresh coat of paint or a DIY distressing job. A changing screen may be just the thing you need to conceal tangles of electronics cords near the wall outlet. For a no-fuss fix to your wall problem, all you need is a few coils of plastic stringer lights and a little imagination. Drive nails or push pins into the wall, then loop the lights around them in whatever configuration you find appealing. Colored lights are the more festive way to go, while white bulbs will be subtle enough to suit just about any space. Have fun with your stringer lights by twisting them into words or symbols. Naturally, string lights double as a source of illumination. Their soft glow can be perfect for when you want it dim but not too dark. Board-and-batten is an accenting technique that involves layering thin boards over an existing wall to give it added visual texture. The boards are arranged vertically or horizontally, or at intersecting angles for a latticed look. This unique design style can be a practical answer for those looking for a less conventional way to freshen up a sitting room wall. Board-and-batten is relatively inexpensive and simple to install if you know what you're doing. If you're not confident in your ability to tackle the project yourself, call a professional contractor to come in and do it right.
Use wallpaper to create a focal point. Set up a changing screen. Tack up some stringer lights. Try out a board-and-batten finish.
