This is probably dumb but I have no idea - can you put clothes over wool or is the wool always supposed to work as the cover and clothes? lol
All this wool talk has me wanting to learn how to knit.
That might take a long while for me to be good enough to do a diaper, but I will definitely be buying one that fits DS soon and one to fit Baby Girl this winter.
Good luck! I have one wool cover but it rarely got used because I had to handwash it and all my handwashing items just get left and ignored. If I had more wool I'd probably use it more but I don't see it being very useful because its so hot here most of the time that longies wouldn't work and shorties, while cute, aren't that much different than regular covers.
