They poo. Copiously. They have neither the time, inclination, or, ability to be bothered about poo on their fleece. And they sweat.
All this is fine. I can handle the thought, I don't even mind the smell. But the actuality had not occurred to me until I was given some fleece.
I researched on the web and I asked friends. I came to the conclusion that for every ten spinners that you ask what to do with a raw fleece you get eleven answers. So, nothing for it but to dive in and give it a go!
I am now waiting excitedly for the postman to deliver a set of hand carders which I have ordered from UKHandspinner. They are in the post!
