Ever seen a room that's been decorated to within an inch of its life? Whether it's matchy-matchy or the obsession with tschotskes, elaborately decorated rooms almost never work unless you're a sultan, prince or madam. When you go to sell, those custom made wall fixtures, the wood accents, the specialty paint finishes and elaborate window treatments will fall flat. Even worse, potential buyers will be so shocked by your excess of zeal that they won't appreciate your home's lovely bones. If you think your room design may be taking things a bit too far, you've probably already crossed the line. Embrace simplicity. It's easier to live with and more likely to appeal to a prospective buyer later.
