for the look you want, I'd consider roman blinds...a denim/soft blue with cream trim would look nice.

i agree. Maybe just some linen Roman shades. It does not look like you have room for curtainS.

Simple, white linen curtains that match your trim. Unfussy. I think if you go with pattern or match the rug, you will get a very serious, traditional feel. GL :)

Not a Pro.

What a lovely room! Beautiful rug!

I would keep it simple. I love what @Color Zen posted.

I agree, drapes or shades in off-white will focus the eye on your beautiful carpet and also what seems to be a nice view and are certainly also nice windows. Keep it simple, clean and classic. Some wonderful paintings on the wall will carry the eye upward from the carpet. What a sweet kitty!

Thanks you for your suggestions and comments. Very appreciated, it gives me a lots of ideas. I like the idea of ​​keeping everything neutral. I like the checkered curtains maybe off-white and cream.

Post a picture once you update your room. I would love to see it.
