Just an opinion here :) I've done the one drape thing many times, and will do so again in my master when I'm finished, but I think there is a couple of key issues with one drape that you're not going to have. First, you don't see one drape hung straight as you'd like. It's just not done. You see the top spread over the window area and then the soft drape to a tie back. Either a tie back or a softer treatment using a loop on the bottom corner of the drape and hooking it up on the wall about half way (sounds funny but basically it is like when you pull the comforter back half way at a hotel so you can see the bedding and the comforter). I can take a pic later since this is what I have in my master bath. The second look is more modern, but needs to be done only on a square window. The long windows give too much drape for the clean look. In your case, given your preference for modern clean lines, I honestly wouldn't do one drape on those windows surrounding the TV. You need a drape on both sides of the window and the span is too far for one rod. It will look odd, hung at the right height or not. But on the far wall where your windows are closer I would give the one rod idea a try. I think if you do a nice clean lined drape on each side of those windows it will have the feel of a finished single window treatment. I'd hang some art in between myself, but that's for you to decide obviously :) But on the TV....you need two drapes on each side. I don't see any way around this. You didn't ask, (in this thread) but I didn't get a chance to reply about the cornices. I LOVED those fabric covered boxes with the nail heads. In your room I could easily see those over your windows done in either a chocolate dupioni or a gorgeous texturous linen. Honestly I think your room is able to take the softer look of a single draped curtain if they're the right ones. Your style isn't "that" modern. It's clean lined, and lovely (i love the room) but it's rather transitional. I think gorgeous chocolate dupoini's draped to each side of the windows with a simple tie back would be fab. Something like a heavy cord, but no tassels, or big soft gold chain (ie lamp chain) on a nice hook (antique gold in color) etc. And that's my opinion for what it's worth :oP

You could do a wall mounted rod bracket (on the wall next to curtain/window wall). Not the best, but the curtains will cover the windows where inside mount will still let some light in.

Eam44- sorry my grammar is broken, lived up north, way down south and some Korean and spanish mixed in, most likely I talk funny too, lol. I do have a 4” backsplash on other wall that is my formica countertop back splash that I am replacing with a butcher block type counter in the future and that will not have a built in back splash, then hopefully continuing tile to that counter space. For the meantime i would like to paint that area under and up sides of window for now to match tile that will be behind stove and that also matches my new cabinet color throughout the entire kitchen. Thank you for responding. Opposite wall in kitchen has an old dresser that I refinished with other uppers. All getting new paint. I have been on HOUZZ with this similar dilemma previously, and received great help, I believe that I will have to seal my shiplap areas for tile application. Clear as mud?

@HU-36691265 - Sorry for confusion - I can clearly see the middle windows are separate! it will look great doing inside mount with a single shade for each window! It would also look great outside mounted but you won’t know your options until you find out how much space the header takes for the style of shade you decide on. It might be really tight in space between molding top & soffit on that right window. If you’re needing window treatments for your entire house, it’s worth it to have someone come to your house. @Flo Mangan mentioned Smith and Noble & there are others - Budget Blinds etc. They all have many styles of shade & blinds & are really helpful. You might get a new house discount if you ask& are doing all the windows. @Lorraine Blasetti - Drapes have been discussed at length & don’t work in this situation! The OP prefers drapes too but has wisely moved on! 😊 Blinds also come in fabrics i.e. Silhouettes etc.
