Well, I can't give you a straight answer. My search-fu is weak tonight.

However, for discussion, I'll add this:

The article says that you loose between 25-38% from raw wool, depending on breed.

I guess it really depends on how much wool a sheep produces per shearing., and the breed, etc....

Kind of a "All the wood that a woodchuck would chuck if a woodchuck could chuck wood." kinda thing.

Anyone? Anyone?....Buhler?

ETA: Sheep are shorn once a year and produce between 6 and 18 pounds of raw wool.....
