After deciding to paint over the stock oak finish of one of our bathroom vanities, I removed the door and drawers and hardware. The high gloss paint I first applied produced an odd effect - the grain of the original finish seemed to show through, producing an uneven appearance So after a couple of coats (and one of primer), I covered it all with semi-gloss black. The end result is much preferable.
(This picture is actually of the high gloss, but it gives the effect. The mirror above the vanity is also painted.)
The house is finished, and here is the front view. The lighting doesn't allow the true colors - the window trim and porch posts are a light tan color; the porch floor is glossy white.
Here is a closer look at the door. The door knob is actually a small brass screw. We will be looking for some hinges on a thrifted item in the coming days. (I didn't want to spend as much on new hinges as we paid for the dollhouse itself.)
