Only thing I’m going to (have to, unfortunately) buy today is a round in a couple dryers at the laundromat, because I’ve put it off too long already and the clothes line is currently a no-go due to weather. sigh

It’s really just that it 1. makes it easy to judge that you have a good ratio, and 2. gives you a start to intermixing them. You really shouldn’t leave it in layers, except maybe to have some dry stuff on top to help keep it from drying out. Mix as thoroughly as is reasonable.
