I have been sewing for 52 years and have made window treatments! One would be easier and would look better but what If she wants to raise only half the width of the windows or each individual window? That is something to consider. Are there only 4 windows?

I think you could do either. (one, or three)

if you did the large one, sew in a vertical solid color border for the seams

fabric where seams aren't noticeable

Thanks Bev, there are 4 windows, all stuck together, but only the two side ones are casements that open out. The two center windows do not open.

She could actually still open the windows when the shade is down because the windows open out though.

Thanks Beth for all of the pictures! The green striped pic looks a bit how mine might turn out if I did one large panel. The one with a border might be interesting too. If I did that one, what solid color border would you recommend with my fabric? I think I could do rose, green, or cream?

Since it's for your daughter, I would choose rose! It would look very pretty with your fabric. Happy sewing!

Thanks Bev and Beth! I will ask my daughter which ribbon color she likes best.

Beth, thanks for the paint colors! we did already paint. the walls are very neutral, Benjamin Moore soft chamois. I love your paint choices though, esp. the pinks. Might be good to do some furniture in those colors!

I think one large panel will be very heavy...perhaps too heavy for your daughter to lift on a daily basis. I would do it in 3 panels ...one each left and right; the center covering the two non-opening windows.

Blubird, i didn't think about it being heavy. I am doing blackout liner, which is pretty heavy, so maybe you are right and I should try to do three. A bit more work, but it makes sense. Thanks!

If you are doing black out I would not make it all one piece. It is too weighty and awkward to pull.

Thanks Kendrah. Yes, it makes a lot of sense.

I will do three shades now.

Should I still do the vertical ribbon borders, or would it look too busy since there would be 6 ribbon stripes basically, with 2 stripes on each shade? maybe I should just do a little ribbon on the bottoms of all three instead?

I have made roman shades several times--for that window, I would make 2 as it gives you more versatility.

Another option is something my mother and I have made for years, something along the lines of this:

BUT instead this is what we would do: either use a rod in the window frame or a curtain rod above the window as if it was a regular curtain panel.

We used the ribbons to tie up the curtain (they would be closer to the edges of the curtain) and when drawn up, the curtain had a lovely soft ballooning effect in the middle. The ribbons were tacked to the fabric at the top to keep them in place.

Whenever I had these, I would get many compliments and exclamations as it's not a standard curtain design. Just another idea. I think if you wanted to see similar looks, you would need to Google "Ribbon tie curtain panel."

IMO that width with one shade will be very heavy

One blackout shade would work fine. But I agree that three would be the better choice for your window configuration. Your fabric choice would make seams unnoticeable as long as straight seam and pattern match. A good lift system for any shade, especially a large heavy one, is a continuous cord using 30# brackets and clutch, 15# brackets and clutch would work on each of the three. What age is your daughter? Keep in mind cord systems to prevent strangulation. There are blackout linings available that are lighter in weight and softer than what has been fairly standard for years. Blackout linings also require a little more effort to develop the 'memory' for worry free folds.

Whether you go with one large shade or three separate shades, change out the window cranks to butterfly type, which can be purchased at almost any decent home improvement store. The cranks will catch on lift systems and create a crooked shade and/or broken shade components.

Hmm... maybe consider shutters on the center fixed windows and a roman shade on the casement ones. Just a thought.

I think I’d do a box-pleat valance and blinds or a lacy/sheer curtain. It’s a big window for one roman shade, and I think separate shades looks unintentional.

This style, but not this ugly, obviously.

Sorry, but I'm not agreeing with some of these replies. Since there's four windows (even if two aren't functional) with molding between them, I don't see how three will look good. I think either one or four. JMO.

Will it be inside or outside mounted? If it's outside, one will definitely look better, but you could mount four onto one long headrail.

Matching seams (if doing one wide) should be fairly easy since you have stripes. Just join them at the edge of a stripe and it should not be too obvious.

If you make one, you'll need more rows of rings, closer together, and you should be okay.

As Connie Elaine mentioned, you should use either ladder tape or shroud tape to make them safety compliant.

Another thing you should be aware of if you're not already, is that you're going to have lots of light holes from the blackout lining, even with the newer blackouts.

Have you considered perhaps making a padded balance board with your stripped fabric then mounting a room darkening window shade? It might be worth considering.

Wow, thanks for all of the feedback! Lot of new ideas to consider!

Anna, the shade with the ribbon ties is so sweet. I would love that, but I think we need to do blackout liner as my daughter is a very light sleeper. I think with the blackout, it would not hang right if just tying with ribbon. I love that look though, and might do for another room.

Connie, and Shadylady thank you, wow, so much to learn from your posts. I will have to save them for reference. I am not familiar with a lot of the products you mentioned, but will look for them. I would love to be able to have a more professional result!

My daughter just turned 10, so I am not as worried about the string, but definitely will look for the safety products anyway.

Katie and Christy, I like the idea of a valance and some curtains underneath also. I think that would be easier for me to make. Do you think this look can still be in style though? Or perhaps it would look too formal for a young girl's room? I will look through houzz some more for inspiration too.

thank you so much!

Not at all too formal. That’s what I had in my room growing up and where the idea came from. Make the curtains a Light/flowy material so the whole look isn’t too heavy.

I currently have this in my east facing guest bedroom. It is a clean yet functional look. My window however is a large slider 58.5 x 48. I mounted The shade brackets inside window frame and made the valance deep enough to hide a curtain rod for sheers. If you didn’t want to make a valance you could do the room darkening roller shade and still make your cute shade (just not a functional roller shade. That way sewing holes and lining weight would not be an issue. Good luck.
