I bought some M&S curtains for DD2's bedroom and they look very nice but I failed to notice that they were unlined until I got them/put them up/had DD2 in our bedroom every morning at 6am since ...
So now DH is saying that we HAVE to line the curtains to make it just a bit darker in her room so that hopefully she'll stay in bed a bit longer but I'm not sure whether I need special black-out material to sew on to the back of the curtains or whether I just need a second layer of dark material or what.
Has anyone done this and, if so, where did they get the lining from as everything I've Googled seems to cost more than I paid for the actual curtains.
TIA for any advice
