By Alexa EricksonPeel-and-stick wallpaper is an easy way to transform a wall into something creative, inspiring, and ultimately, a piece of artwork that serves as a focal point for the room. Peel-and-stick wallpaper is especially useful if you live in a rental or otherwise want a temporary wallpaper solution.The process of hanging traditional wallpaper involves pasting big sheets of the paper to the wall in sections and working out bubbles. Meanwhile, peel-and-stick wallpaper is essentially what it sounds like: It comes in a roll or on sheets, and you peel off the backing of the paper and adhere it to the wall like a sticker.In this guide, you’ll learn how easy it is to apply peel-and-stick wallpaper to transform your space in no time. And, the beauty of peel-and-stick wallpaper is that it’s even easier to take off as it is to put on (unlike traditional wallpaper, which is notoriously laborious to remove). That way, if you change your mind about how you want to style a room, you can easily swap out your wallpaper for another print or color in no time.
