I am so glad that you do not pull that brown blind down! I would remove it pronto ( I guess you can tell that I abhor brown blinds !) Can the sofa at least be pulled forward enough to let the curtains hang straight? If so, get a decorative rod so that you can use grommet top ( or curtains with rings) drapes.

I would be careful when choosing a patterned drape ( no tie backs). You might want to opt for a neutral, lined , solid color. The grommet top drapes can easily be pulled closed if you need nighttime privacy. You will need 4 panels for that window so that they look full enough.

I see the dilemma.... the drapery really loses it's look of, "drapery" curtains, etc. Why not use the blinds and put a simple on trend, "valance at the top outside mounted about the window or a style of Roman Shade over if you don't like the blinds.

I personally think the blinds would look nicer than losing half the curtain. A half curtain IMO would not be a great option. Since it's a sectional you can't have the panels down each side to the floor, etc.

Or a topper would be my next option/suggestion.

A topper such as an inverted box topper or a partial roman or relaxed roman would be nice. The shutters actually don't bother me at all.... I prefer them over your dilemma with the couch unless you can pull the couch out a bit so they can hang nicely. I'm sure you've tried that option already though!

Any fabric under the sun you could opt for. Just examples of some options!

Many options...... The inverted box that is sketched and or the roman or relaxed roman topper in a nice solid would look nice and it's not dated. You seem to be on the right track you found something above. It's a bit heavy, but not sure how large the room is. You could do three roman as long as they touch otherwise you will see the wood peeking out.

One long one would be fine too as long as your fabric wasn't a heavy fabric such as a velvet :) then lined would be heavy.. just an example.

The full Roman posted above the window seat shown above is fairly long and no issues.

It's very nice, neat and updated... I have relaxed in my family room and have 4 windows. Two of the windows are similar in length to yours and no issues. I keep the blinds behind them up and out of site as I keep the Roman up partially as it looks pretty. I can lower the blinds if I want to at night (if I chose to) and not have to lower the romans they look most pretty when pulled up as in the photo above and blinds are behind.

I'm typically not a, "scared" person. Some need privacy some don't like myself. We back to the woods so deer can see in and maybe a person if they want to walk around a very deep lawn around the back and peek :).... Yet, after 5 years of having them I've had no issues.

I do like keeping the ugly white 2.5" blinds up behind them if I do want to shut out the world :) I can drop them.

I would suggest an outside mountRoman shade with the navy/white theme you have going on with your lovely throw pillows/vibe in the space!

This is SUPER sassy!

Or perhaps something a bit more subtle, like this:

Roman shades can have a top down/bottom up operation, which is SO useful in maintaining your privacy, and light control.

This is a bedroom, but just look onhow sexy that Roman shade is? DEE-lightful!

Me too and very rarely close the wood blinds from behind the relaxes romans in the house so if you can get a nice roman or relaxed roman you can keep them/behind decor and close the blinds when you need privacy or to block sun.

Please post when you choose and put up what you want... keep it simple!!!
