Cool idea for small home decor
I'm probably the last person to see these, but here is a company that makes peel 'n stick appliques for tile! They have a variety of different murals, as well as blank stock to print your own. They are washable, and peel right off. They can be used over, so you could change your backsplash to suit the season/mood. The website isn't very intuitive (for me, anyway), but the product links are on the left. What a boon for those of us who have a hard time making up his or her mind!
