I would say 2 pieces of curtains could be used to cover these two windows from left to right and from above the window frame to the floor.

However, the left and right 2 sides of the window frame are basically at the edge of the wall, the layout here might look particularly cramped.

So using some curtain tiebacks to create some space to make the whole space look more chic and fresh would be a choice!

Or I would suggest decorating the larger window first, and using Roman shades, blinds or decorative paintings to cover the smaller window on the left. Here are some inspo for the larger window treatment.

You have a heater there so drapes are not really going to be functional. I would do a nice roman shade on the large window and leave the small one.

Sometimes you look and something and you just gotta ask, why? what were they thinking?

Thanks all! i think i might make custom drapes for the window on the right, have them pleated and half the standard width, at 27” wide each panel, and only use them for decorative purposes so they wont ever be closed. I think i will use a French Return Rod so it uses the least amount of space.

Then i cant add a roman shade to to the smaller window using the same fabric.
