Diana, as her Inside Out tour indicates, is innovative at every turn...
Diana's contractor salvaged french doors and refinished them. The glass panes were a little too revealing for her bedroom, so for color and privacy, Diana added vellum sheets cut to fit.
At night, the doors look like solid bursts of color, and during the day, the panes become transparent, changing with increasing sunlight.
Cheap, easy, utilitarian, cute!
