Do they exist, can anyone recommend some? We’ve got a really crap track rail for our curtains that doesn’t cope with heavy curtains and a tall, fairly wide bay window, so replacing the track is expensive and difficult. I have a cheap and cheerful pair of curtains up atm that are very light weight and fine in the winter as we have shutters too however I’m waking up earlier and earlier because of the light levels. So can anyone recommend really lightweight blackouts?
