Those widows were built to be covered with center draw draperies down to the floor.

Thank you! Recommend the drapes span the full wall or just around the window? If the latter, how much additional width beyond the window? (I'm overseas and have a possibility to make some linen drapes...) .Same window dimension is on the other side of the room as well.

"Curtains found in model homes and design magazines typically hang at least 6 to 15 inches further away from the window on each side. This creates the illusion of a larger window, taller ceiling, and gives you the option of beautifully framing a window."

If you want to expose the entire width of glass when the panels are opened you need to find a stack back chart to figure out what finished width will permit this.

Make a personalized one roller blind, hanging there like a artwork. good looking and afforadable.

Thanks however I want to let in maximum light--seeking to give the room more character, doubt we will ever close the drape/blind..

If so, solar shades will be suitable.
