There are spaces that offer little architectural detail. But I subscribe to the thought there is no problem a little fabric and lots of color can't solve. The empty bedroom below was nothing special. It's located in a stately Washington, DC mid-rise building near the National Cathedral. The occupant has a flair for color and a strong sense of style. Sheer fabric was used to drape the adjoining walls behind the bed. Bead fringe swags topped it off... now, that's special.

A large bedroom window was draped in the same sheer style as behind the bed.
