Has anyone got these? Do they really exclude all light? I'm getting desperate. The dcs have John Lewis blackout blinds and some curtains with blackout lining and are still waking at 5am (and refusing to go to sleep in the evening).
And has anyone seen anything similar but smaller, or know if they could be cut down in size successfully? I'm not sure what they're made of, and if it would fray. They're twice the size I need for the dcs' window.
And how easy are they to remove from windows? I can just imagine ds1 would pull it off.
