Hi Jamie. I see you are having the same “I” problem I have been having with the ? Coming up! Another glitch;)! Anyway, if you do the cover you may want to make it larger on the left side so it overlaps equally. Then you can do stationary side panels on the outside of the windows. I know you may not want to go into your window trim but a good finish carpenter can make this look good and then all will be centered!

Of course with your nice woodwork you could just do Roman shades.
