Has anyone got blinds that you can move up and down as required? If so any drawbacks with light tightness? In the U.K. it seems that only Firstcall make a self assembly kit to the user's measurements. Not cheap. Prices start at about £186.
It would be great to occasionally have daylight when toning and it might even be possible to have a window slightly open for ventilation without affecting light tightness.
Has anyone got Firstcall blinds or if not where else have you obtained blinds and at what price for what size window?
In full daylight and especially on hot days my current blinds which are hung from the former curtain rail( it's a converted bedroom)I and then fixed with velcro have a tendency to open slightly. Even this time of year I find myself running a hand around the velcro before a session to be sure it has stuck all round the frame.
