You can buy repositionable wallpaper on the web, in some home furnishing, paint or "big box" stores. But, beware when buying that you compare quality, size and properties and not just price. All repositionable wallpapers are not the same. For instance, some require moistening with water to apply. Some adhere better than others. Some are very thin. Some are more prone to collecting air bubbles than others during installation. Thicker ones more easily cover and mask any irregular surfaces. And then, there are those which are not only repositionable and removable, but also reusable. Making the latter type ideal for students, rentors, and anyone who want to decorate seasonally.
