I'm still working on the re-do of the bathroom interior. I will get a chance to work on it this weekend, since my girls and my husband will be gone for a couple days.
The original color of the door was this lovely orange wood tone which dominated our early 80's home when we first bought it. I've since painted it all white. Check out my kitchen.
My door already has the recessed rectangles, but I have seen people do this with tape and a ruler.
This would also look good in an upstairs hallway, you could paint all your bedroom doors.
See that little blur running through the bottom of the picture? Not a ghost, just my baby girl.
