Just saw this- we have them- they are great as blackouts and I think in the depths of winter they do make a bit of a difference in terms of warmth. We got them for 2 bedrooms and then got 2 more for the other upstairs rooms- blinds2go I think are great. The sizing was perfect too.
Thank you @Unicornconfettiicecream, that's really good to know. Glad you're pleased with the blinds, and with blinds2go. I've just received some samples, so reckon I'll be placing an order, once I've decided on the colour.
