At first I was skeptical it would fit our extra wide door, but it did look pretty long, so we measured and it was about half an inch short. I knew I could make it work.
The valance was also pretty ornate when we found it, with some serious molding. We thought we might use it as-is, but it really didn't fit in, so we stripped off the molding.
Once it was cut to size and sanded we started painting with some primer.
Then we moved on to the final coats. The top and bottom are white with a thick stripe that matches our cabinets. It's subtle, but adds a little interest.
I wanted to make sure it was mounted securely, so I used four L-brackets to mount it. Snapping a chalk line made this part much easier. I also shortened the rail the blinds hang on so it would fit in the valance.
Here's what it looked like before:
