One of the easiest and simplest ways to give a bedroom a big wallop of design is with an accent wall. You could make the case that the best place to do this is behind the headboard, because the rest of the room should bow down to the place where we lay our heads, rather than compete with it, right? The process can be as simple as painting the wall a different color. But with options available today like 3-D cement tiles and mica wallpaper, you might want to consider the range of choices before making a decision. Check out some of these beautiful and creative ideas for bedroom accent walls.
