You don’t mention if blinds will stay when adding new drapes. But consider having drape rods at same height with both drapes going to floor.

Thank you. Yes, blinds will stay.

I don't think drapes belong there (I know you didn't ask so feel free to ignore). But they will bunch up behind the bed and seem kind of overwhelming on that small window in such a small room.

Cane roman blinds or ceiling track affixed to ceiling for ceiling to floor drop netts.This will extend the rooms look an make it softer by far no need for drapes if 3xs thickness of curtain netts .

I agree with sharp Roman shades.

If you want to keep the blinds, maybe it's possible to do stationary Romans so they stay midway.

It's a lovely bright room. Less is more is smaller spaces.
