...but something in between...
I am after a roller blind to fit behind shutters that will cut out a fair bit of light, but not ll of it - so when the shutters are open and the blind closed, there will be enough light on the room to see but I still won't be dazzled, till I'm ready for the day. The thickness of a fabric curtain I suppose.
Does "sheer" just mean "not blackout"? The pictures I have seen (Dunelm, Ikea etc) look like they are more like nets for modesty than for shading out light, and I don't think these would keep the room dark enough at night. But I assume the blackouts do as they say. Once upon a time roller blinds did neither of those jobs very well because they fell in the middle somewhere - and one of those is what I want, awkward bugger that I am!
If anyone has found this mythical beast, I'd be so grateful for a pointer 🙏
