Or do you throw it in a "Handwash" setting (or other) in your washing machine?
I never used to buy handwash only clothes on the basis I'm not going to do it. But I do love cashmere/wool and have slowly been accumulating jumpers and cardigans that are handwash only. I mostly don't wear them a lot because, again, I'm not going to handwash more often than I can avoid.
I have a good washing machine, it has a handwash cycle - it's fine, isn't it? I'm not going to ruin anything, right?
