A single roll of wallpaper may not be enough to cover an entire room—but it can still transform a space in an impactful way. And since many patterns are as beautiful as artwork, it makes sense to display them as such. To keep the paper smooth, mount it to a thin foam board before framing. Line up several panels of wallpaper for the most dramatic effect. The best part: You can easily take this wallpaper down and move it around, or even bring it with you when you move.
