There are certain absolutes for designer Erinn Valencich. Hang the draperies close to the ceiling. Paint the ceiling the lightest shade in the palette of the wall color. And if the walls are a deep or dusky hue, make sure the moulding is white. "That's non-negotiable in my book," says the HGTV host. Those rules came into play when Valencich remodeled a 1930s, Spanish-style home in the Hollywood Hills. Inspired by the Viceroy Santa Monica hotel, she repainted the faux-finished orange walls a rich charcoal and the dark moulding a lively white. Fabric she'd picked up as an impulse buy - "it was so cute, it showed monkeys climbing on trees"--was used to make generous drapes. "Hang them 4 to 6 inches from the ceiling and extend the rod at least 10 inches wider than the window," she advises.
