I'd say I do about 1 load a day on average but sometimes that means 3 loads in one day.

We have two adults and one toddler.

I'm with you Hollye - I reuse towels because you're clean when you dry yourself so in theory they're just wet, not dirty. When DSD lived with us she was a bugger for getting a new towel for each shower so I ended up giving her two towels and hiding the rest in my wardrobe.

But yep, I don't wash sheets, doona covers nearly as much as I should.
