Pleated and lined curtains off the shelf, but an acquaintance with a blind stitching machine properly hemmed them for a small fee. Only thing I changed was the location of the side tracks. For some reason they are almost a foot off the side wall. I moved them to 3-1/2" off the wall which greatly increased the "volume" of the cabin with curtains closed, not to mention the usable surface on the dressers. (Used a 3/4" x 3/4" piece of mahogany (sapele) to span three places where I could fasten it, and screwed the track to that.) And as you can see, the Admiral is using that surface!
Before and after.
