I've been wanting to jazz up my little condo kitchen for a while, but since I'm renting, there's not much I can do about the cabinets or countertops. What I came up with was using wallpaper to create a temporary backsplash.
I used leftover wallpaper that I had previously used in the adjoining dining room so that it tied the rooms together. This paper is strippable so I can remove it when I leave and it won't harm the walls. I put a coat of polyurethene on top to help protect the paper from splashes.
This was a no cost, 1-hour project, and it helps spice up a standard kitchen, don't you think?
