I have a dormer in my loft with a large crittal-style door and Juliet balcony. I need to put some kind of window dressing in to block the light (it’s a bedroom. The challenge is, there is <5mm of clearance between the top of the door and the ceiling. So nothing top mounted will work as you couldn’t open the door. Can’t do in-frame blinds as crittal style so lots of panes. Could do bottom-mounted blind (would need to attach to face of window sill ie face into the room, not on Top of window sill as would block door). But that will need some kind of side cords...and they all seem to have brackets that attach to ceiling (and would block door). Help! Does this exist or have I stupidly created an impossible window?
