I have transoms. One thing I had not thought about until I started looking for window treatments was the height of the "stack" of blinds and roman shades when the treatments are fully open. The "stack" (i.e., the slats when stacked up when the treatment is fully open or up) on wood blinds is very thick and the stack would have covered up my transoms completely on my taller windows (I wanted inside mount) and I wanted to be able to see the transoms. All the blind/roman shade manufacturers that I looked at provided information about the "stack" height, so it's easy to get that information. An interior designer that I know says that wood blinds are really intended to be kept down down most of the time and then you adjust the slats to let in light/view. But we live out in the country and have nice views and I didn't want to be looking through slats when I looked at my view. Good luck.

Your place is more MCM than you let on! I have seen photos somewhere of a solution to this. But for the life of me, I can't remember where. What the person had done was: make a cutout the shape of the window out of something substantial but not too heavy -- maybe a piece of lauan wood or oysterboard/foamcore? Then it was hung in front of the window on hook eyes or something. Then a string was attached to it, and run up to the ceiling through an eye and then down to where it could be secured on one of those little cleats on the wall. That way the string could be pulled and it would pull the cover "up" to allow the light in. But most of the time it just hung in front of the window. It could be painted the color of the blinds below, or you could take the opportunity to put a graphic on it that the kids might like.

@JudyG, THAT is just plain BS. Just because you put quotes around your own fairy tale does not make it true, nor does editing your answer to something else just as wrong. I will repeat - until you come up with an actual published code, quite trying to claim it exists - much less add the word "most" to your supposition that there must be that one pot of gold at the end of some rainbow someplace to support your crackpot theory. "First in many jurisdictions, it's not legal to have a stove in front of a window." Still a bunch of nonsense no matter how many times it gets repeated on here. You will notice that not one of these people can ever come up with an actual code that states this, no matter how many times I offer them the opportunity to prove it in the last 5 years. The only time it is not legal is when the installation instructions are not followed in the first place, regardless of window placement. It doesn't even make the list for hazardous locations in section R308.4. https://codes.iccsafe.org/public/document/IRC2015/chapter-3-building-planning The Listing and Labeling of ALL cooking appliances contain clearances to COMBUSTIBLE materials ONLY, regardless of any intervening "protection" applied to that combustible material. There is no such thing as a different clearance to a tiled wall or any other non-combustible covering. There is no differentiation in the code, or the testing standards the codes refer to as to whether there is a window in the wall above countertop level, or how far from a window a cooking appliance would have to be if it were a requirement. If there is no minimum distance stated in the code, then how can it be a requirement?? Is it 1 inch or 10 feet? A window on each side of a range will produce the same cross wind as one over a range. Anybody who has 2 broken arms so that they can not shut off the burner for 2 seconds to close a window, probably should not be using the stove either. If the range allows the wall or window behind the range to get over 194°F, then it is the range that is in violation of the codes - not the window. Of course, we all know that CP's little community over the rainbow has gathered every old wives tale code that ever managed to make its way onto the internet, and amended their legal code to make sure they didn't leave any out...They can't even put expansion joints in their concrete slabs because if you end up stepping on a crack, you would break your mother's back!! If you want to watch the "fairytale code" people have a coronary, just skip the hood ;D

I would not spend the money to get customized Roman blinds for that window unless you really like the shape of the window and want to highlight it. Just get regular blinds and have them mounted on a board at the top of the window to compensate for the thickness of the trim. It will obscure the shape on the top, but will give you good light control. You could get a pretty print. You could do the same with Venetian blinds. I like Venetian blinds for the bedroom, because you can open the slats to get in light and people can't see into your room, whereas a Roman shade has to be opened wide to get in light. One last thought. I have never had a headboard for my bed. But I have had a quilt hung on the wall over my bed for years. (It is a piece of art.) I've never had a problem. So if you allow a couple of inches between the wall the the curtains, it might work for you.
