Several months back, I went to the Oregon Flock and Fiber Festival, and picked up my first unwashed fleece; I got a ten pound bag of unwashed border leicester lamb's wool. It came from SuDan Farms, in Yoder, OR. Working with it has been a great learning experience.
I documented the before and after, plus my process, plus lots more pictures, over here: http://www.miloknows.com/2013/01/how-to-wash-fleece.html
After washing, I dyed some of the raw fleece before carding it.
I am starting to card a lot of this stuff now--it's definitely a different process working from wool in this state than from roving or prepared batts. I'm finding it easier to use handcarders to open up the fiber first, before putting it through my drumcarder.
I have some finished batts ready to spin now (exciting!).
Moral support, comments, advice appreciated!
Here's a sample of the finished yarns from these batts.
