I'm after a screen as per title. It must be no more than 170cm wide but needs to be very long as it will be high up, probably something like 2.5m! What I would like is one with a spring loaded mechanism so I can pull it down with a hooked rod and then secure it on a screw or nail in the wall and it will slide back up once released. Any ideas where I could get such a thing? doesn't have to be brilliant, just after the effect really.
