Have curtains (cream) and a blind (cream) neither of which remotely keep the sun out and am wide awake with scorched eyes at 4.30am at the moment! rather than do what I did last night every night (hook another duvet cover over curtain rail) do you think I could take the current curtains to a sewing shop and get them to stitch some black out lining in? Anyone else ever done this? How much do you think it would cost?
