I have a lovely flat with a big bay window. LL had blue Ikea things that looked like shower curtains up, which I replaced with less offensive voiles just to dress the window a little.
Now that its colder, am I losing a fuck-tonne of heat by not having proper curtains? Also, I hate the look of short curtains but long ones would cover the radiator.
I also feel like decent, lined curtains will cost a small fortune for the size of the window. Have attached a picture, I think it looks ok without proper curtains.
