On a sheep! I'm sorry. :-)
The last time I used wool with kids I was working at a school that had a model
farm with sheep. We made felt balls and experimented with carding and
spinning, but I never got the spinning down myself.
If you do a search for "raw wool" you may find what you're looking for.
