I also painted the wood "backsplash" in our kitchen. Luckily the builder actually used wood in here instead of MDF like everywhere else in the house where there's moisture (i.e. every bathroom). Now we just need to get rid of the brass knobs! I also want to eventually replace the microwave with a pretty stainless hood.

(I've also cleaned the microwave vent since this picture was taken - yuck!)
It really bothers me that the kitchen cabinets don't go all the way up to the ceiling, but at least someone enjoys it!
