Can't afford to wallpaper your whole room? Not allowed to wallpaper your rental? Instead, cover a cheap sheet of plywood or even cardboard with a patterned wallpaper. This trick still makes an artistic statement, but it's not permanent and it's also portable. Take it with you when you move! You can make more of an impact by papering a couple of panels, or several, and placing them around your room to give it cohesion.
Despite the fact that the room shown is quite simple, with a no-frills and tablecloth and reserved chrome armchairs, the patterned paper still makes it eyecatching. Better yet, it's easy to change the wallpaper when you want to stir up the look and feel of the room!
