If you want to see your window trim, inside mount blinds will do the trick.

Yes, inside mount shades ( lots of options ), preserves the pretty view ( Idon’t get snow where I live so it looks pretty to me ). .

The drapes need to go away if you want drapes they need to be MIN 2.5x the width of the rod and if you go with that very light weight fabric I like 3-4 x the width of the rod . You to inside mount blinds if you need them if you do solar shades they will allow you to keep the view during the day and mixed with drapes privacy at night. BTW they give you daytime privacy

In a room that might have some other design issues? I see no reason for curtains of any variety. Certainly not skimpy sheers. The view is private.

If a sense of warmth, or cozy is the need? Do a roman shade, inside mount, all trim visible.

Tidy up, post more jpegs, and style advice will be more relevant to the window, and more.

love to show off the beautiful trim with an inside mount blind/shade.

what are the sizes of each window separately?
