I have 3 kids and do the laundry on Wednesday and Sunday, about 3-4 loads each time. Everything gets hang-dried except towels, socks, pyjama-pants, and men’s undies, which go in one big late-night load in the dryer when the juice is cheap.
It takes 2 small clothes horses in my laundry room. Not a huge basement.
Only time I’m doing lots of drying is when I’m washing sheets, which is probably less often than I should.
