It was all going so well but I've had my first mishap: the blind in the bathroom will no longer roll down. It's like a spring has gone in the roller. It gets so far, although it's very stiff, and then just starts to crease the blind. Presumably I would have to fish out all the stoppers and unscrew the fascia to get at it? Hopefully the window won't fall out if I do that? Any advice would be much appreciated. Regards, Lee.
