It's funny, when I spent 6 years back in the 70s living out on the west coast of Ireland, it always felt like I was practising for something! We had no running water initially, and got it from our stream. So washing wasn't a big priority, though once we acquired a Rayburn we could heat up a tin bathful every so often. Washing sheets and thicker clothes was tricky, especially in the winter - never really found an easy answer except to not bother. And yes, Yulia, I used plantago (or plantain here) for cuts and so on - also yarrow.
After I came back, I really didn't like living "normally" and went off to Cornwall and lived in a caravan on a common for 3 years, until we all got thrown off. There was a great freedom in living so lightly - except that it seemed to annoy so many people!
