Too much brown....what other colors do you have in this room? You need drapes with interest and color! OR roman shades with pattern.

Update your blinds to 2". I like the way the curtains hang in the first picture, but Diane is right, there is no variation. Go with a pattern. Start visiting fabric stores and get samples of curtain material. Don't go with a heavy upholstery fabric, it won't drape as well.

New drapes in a nice print and add some woven woods or a lightly lined sheer blind for privacy.
