Thanks all - your input is, as always really helpful in the countless decisions involved in our DIY project. Now to put my decision hat on.... can't ponder forever!!

I would treat the big window and maybe do like a stained glass or faux stained glass insert in a happy pattern in the small window?

Your view is spectacular. Gorgeous drapes you can pull to the sides will “frame” the view, but using blinds strategically for your comfort (and to preserve the furniture) is important. You don’t need both on every window since blinds “disappear” when they’re up. But having a fabulous fabric for the drapery will enhance the view. What a fabulous location! Congratulations.

I’m a bit challenged trying to visualize this room as a whole. I think that how much use for going in/out the sliders needs to be factored in. The front slider next to the window is the most challenging IMO since there’s no room for any window covering to stack completely off the glass on the fixed panel side of slider. I agree the same fabric & treatment should be used for all windows. I think I would hang separate drapery panels over each window. For the front slider & window I’d use the same length panels for both slider & window for a better look when closed. That slider - I’d have drapes that open in middle & pull to each side. The corner fixed panel will always be partially covered with the open panel on left. The drape for panel that slides should stack completely off the glass so that door handle can be easily accessed. The window would be traditional drape open in middle & stack completely back off glass on both sides. Two rods for each window - sheers on inside rod & drapes on outside so the 2 coverings can be open closed separately. When closed, this wall would appear as a complete wall of drapes. As for color - don’t know if you’re wanting dark blue or thinking that’s room darkening. Room darkening drapes are available in many colors. Slider in dressing area should have same treatment but sounds like with 16” space on each side the drapes can stack completely off the slider on each side. Whether that slider has sheers or not depends on the privacy issue. Maybe only drapes on that one - no sheers.
