I have definitely started to wash my towels less since last winter when we was wracking up £15-£20 a day fuel use.
I think it's a bit like covid, you pick up new mindsets. I have recently bought my teen his own colour of towels, so that immediately reduced the amount of towels I had ti wash as he uses a clean towel every day. Now he is certain only he has used it and he has to wash it, it's become weekly gor his towels.
