If you have a large blank wall that you don't know what to do with, consider framing wallpaper! Get some trim molding cut to the proper size at Home Depot and paint it white. This makes for a dramatic (but inexpensive) piece of wall art.
Why choose a type of wallpaper, if you have three favorites? Make a beautiful field division and there is a beautiful patchwork wall. Cut off any wallpaper roller surfaces of several square 52 × 52 cm.
