72" is quite a span. If the windows have separate frames/trims, I would spring for two blinds.

inside mount, for sure, to show off the trim detail.

A Blind rather than roman folded ... Top down, bottom up for light control and privacy control. The come in so many colors.

Why those at all ? I need to have some context and I dislike this type of window covering but what is driving the choice ?

Thank you both.

Patricia, I have a bay of tall windows and a glass door which open from the Master onto the screened porch. The screened porch is set in to a sort of "u" shape between the kitchen wing and the master wing.

I actually like bamboo/natural looking shades, and I would like them on the windows for shade/light blocking (the bedroom has windows West and South, with another tall window on the South wall, not shown). I would prefer not to do curtains, but to keep it quite simple and tranquil. At one point, I had considered a very simple iron rod and floor length linen curtain treatment, but I'm afraid that would be too heavy looking when opened. Here's an older photo of one end of the room from a while back.

This looks a lot like our style, except for the chairs. We like natural fabrics, and I have a collection of Asian ceramics and rugs from which we will draw color, so I try to keep the windows and upholstery as simple and light as possible.

they come in a variety of colors, take a look at the site. I've also used Blinds.com (they often have great sales during different holidays, like 4th of july, etc.)

72 is just on the edge of being too wide. I still think I would do one because otherwise I’d waste too much time getting them lined up. Shame your view is so terrible ;)

WOW you have agreat view why not solar shades they give you heat and UV control and daytime privacy and allow you to keep the view . I usually mix them with drapes if nightime privacy is an issue or roman blinds in this case I get the blinds could be what you like . I sure would not want to lose that view .

If these will be opened and closed every day, you might look into springing for motorized. We got Hunter Douglas ones for our kitchen and it has been awesome. I've also purchased several shades from Blinds.com and have been happy with the quality. The matchstick will add a lovely texture to your room. Such a pretty space!

I also like matchstick blinds and/or natural fibre ones. Here the look with each window done separately of together on 2nd picture.

Thank you everyone for the feedback. I think I may go for one big shade in the middle, because I know it would drive me nuts to have the two at different heights.

Suggest instead a light, soft feel that won’t detract from the view with cordless, lined linen fabric (avoiding fading and deterioration) on each window.

Those beige linen roman shades will take up a lot more vertical space than matchstick blinds, and because they are so neutral they don't add anything to the windows. If you use something like that, you would probably want to add curtain panels for some pattern and color.
