My sunroom has a large window behind the couch which use to be the outside window of our previous back porch. I think I need to add some sort of window on that window to soften it and balance it out. I am undecided between a valance, Roman shades or two long panels to hang on each side on a long decorative rod. Please keep in mind I have 14 other outside windows in the room that my hubby will not let me cover. I have attached photos of those windows to give you an idea of the whole room. Thanks for any input!
