Hi. That is a beautiful wall of windows! I recommend using one large shade that covers both the transoms and the windows. It will give you a cleaner look and better functionality.

Agreed. You could get one that lowers from the top or raises from bottom for more flexibility.

Agreed. However if your supplier insists that the window is too wide for this, get 3 running top to bottom as your wood work will accept this option too. Best of luck!

I've got a couple of wide transoms, and treat 2 ways: one has single honeycomb shade (72" wide) that raises /lowers both from to and bottom--this is ideal for me as I love light and privacy!

The other has curtains mounted below the transom. Again, for light, and I wanted curtains to match other windows in room. Thought it would look odd, but does not and the amount of light that filters in all day is great!

Have you thought about putting window tint on the windows or at least the transom? I agree one shade looks best.
