Roman shades? Is that blue or green in your rug?

You have enough room for draperies. I would get a pattern with orange and browns in it.

BTW, pull the sectional away from both walls a couple to three inches.

I could see Bamboo wood Roman shades in your room, especially with your rug. And baskets, texture....

Can you swing that sofa around so that it’s not up against the window?

I think Roman shades would look nice.
