@romola unfortunately the U.K. is generally too damp to do as you do, the washing freezes and thaws and refreezes, stays damp or gets wet with rain. It rarely dries outside in winter. I do peg things out for an airing if it is dry enough, although I don’t expect it to dry and I have to keep an eye on the weather.
I have just had to buy a new tumble dryer as mine broke down and I don’t have much space indoors for drying. My nearest laundrette is two busses and a train ride away (plus a half hour walk) so that’s not really an option 🤷🏻♀️ Wish it was, I hate the smell of indoor dried bedding (although the smell of scented fabric conditioners is even worse!)
