Try Windowed Doors & let the light shine in!
In every home there will be one magic place where you can install a windowed door to let in light. Instead of the usual solid wooden door try out a French door between rooms. It will be available at many building-supply stores. Even with curtains around the room, the French door will let in light and brighten your home, says the Green Your Home All-in-one for Dummies!
Just find that location in your house which is the perfect candidate for a French door.
And you can do the same magic with your front door. Glass panels can lighten up your entryway, and cheer up all visitors! They will be more friendly than a sturdy, stodgy mass of heavy wood!
