Please ;ost a picture of the entire room. We need to see more of the windows

excuse the very poor rendering but this might work

I don't think you'll be able to mount a rod above the triangle window. It's not going to work out like the rendering. Instead, it'll hit the ceiling on the left. I think hanging the curtains right under the ceiling, makes the smaller windows look unbalanced because of the transom on only one window.

I think you're better off with just shades or blinds in this situation.

You could have shaped curtains made, then hung on knobs over the triangle window, and then hang curtains further down over the smaller windows.

Do draperies/curtains (with separate rods - not one long rod as rendered above) on the wall above the triangle window(s) and above the window(s) with the small rectangular window above it (to the left of the TV). Do a matching or coordinating roman shade on the single window (to the right of the tv— next to the triangle window). Stick to low-profile finials or a black-out style curtain rid so you don’t run into the problem mentioned above and so you have enough room for stackback.

If you don’t want curtains at all, or would still like some light coming in, do matching roman shades on all the windows (except the actual triangle small rectangle themselves, obviously).

Let the trapezoid window read above the drapery panels.

You guys are awesome. Thank you for the ideas
