In the meantime: national sheep breeds.

While I don't finish the marathon that this small study about the wool from portuguese sheep breeds as turned into, here's a little video on the subject.
I'm sure this is a bit outdated by now, mainly because a few more breeds have been made official since then, but it's still very interesting.
In Portuguese only, but you can look at the pretty pictures.
