Cynthia Taylor-Luce These would have been hung on short lengths of I-beam since they are not meant to pull across the window. What a lovely effect, framing the view of the waterfront outside. Even when curtains aren't needed for privacy or light control they have a very important decorative function, as you can see here.

pics4me Thanks so much for your reply. The draperies hang so beautifully!

Letitia Holloway I think these are goblet pleats... Are they? The pleating is another thing that makes these special.
