Here, in the western U.S., we still have hardy souls that like to work the raw wool to completed weaving or other construction methods. Many of them are Native Americans of one Nation or another. I've had the opportunity to observe and learn from the process.
Firstly, if you're sincere, you're about to learn just how dirty and smelly those fluffy, cute little no-nothings are. (Sheep are nortoriously stupid, but then I live on a cow ranch!)
The raw wool must be picked over to remove large pieces of organic material, such as weeds, seeds, branches and small children. The wool also has embedded dirt ranging insize from small specks to large boulders... next, secure three or four fairly large plastic containers. The dish pan size works best. You'll need rubber gloves, a good, mild dish detergent soap (ya'll call it washing up liquid, I think) I notice a lot of aficianados use Ivory Dish Soap.
Wearing the rubber gloves (the wool iis very oily/greasy) place the picked over wool in the first container and fill with very warm water... almost hot to the touch, that's been mixed in a bucket with about 1/2 cup of the liquid dish soap. The water/soap should cover the wool. If you have too much wool for one container use another in addition.
