I went looking...and found stickers to make a refrigerator more than just the standard place where we hang our children's art work (or photos/coupons/whatever happens to be hanging on the refrigerator at the moment). Here's one that looks like a bookshelf.
Or a sticker/wrap that makes your fridge look like an old fashioned soda vending machine.
Or a London phone booth
Here's a dishwasher cover from Appliance Art.
And a cat cover, and vintage dishwasher cover, both also from Appliance Art.
Oh, and here's the original police box refrigerator skin that started me on my quest.
