Do you have flat/relaxed linen Roman blinds? Do they work on big windows, and when they have to be functional, not just left unrolled permanently? I'm thinking about the blinds like on the attached photos. My window is very big, 150 cm wide and more than 3 m tall, but the surface to cover would be around 2 m long (the bottom is wood, it's a French door). I don't really like the normal Roman blinds with horizontal lines.
I have blackout curtains but I need a sort of privacy cover too, so I want linen voile, and if possible would have these relaxed blinds instead of another layer of curtains.
