I feel like I'm remodeling my kitchen, only a little tiny version.
At Restore (a used building supply store) I found these sheet of small tiles, perfect for the play kitchen backsplash and this bathroom sink size makes for a great play kitchen size sink. I had to take the base off to make it fit under the shelf though. I was pretty happy with this find and the price of a total of $12. It will make for a more realistic kitchen I think.
