Updating your space doesn't need to mean cans of paint: Just go for peel-and-stick wallpaper like this. It's made in the USA on matte-finished polyester fabric with a self-adhesive backing, so all you have to do is remove the protective cover and stick it to your walls. It's basically adult stickers, and we're kind of all about it (plus, it's great for renters). And with its pattern of semicircles in bold patterns, this wallpaper adds some major mid-century retro vibes to your home. The pattern repeats every 24'' and has a straight match for easy application.
