I'm in the airport, with only a few minutes to write to you. Since I'm travelling to Shreveport this today, and since that will take hours and hours, and it's hard to spin on a plane (somewhere Denny's hand just shot up and she said "No, no it's not!" because Denny uses her drop spindle on planes all the time, which I don't, so just let it go Denny. Just let it go.) Because of all of that, I'm leaving my wheel sadly behind, and have picked up Ken's Francie socks, and another pair of socks - and I really think I can come home with at least one finished pair, which would be a nice change from all this spinning. Not that I'm tired of the spinning, because I'm really, really not. 
I'm leaving behind two full bobbins of this lovely stuff, which is Manx Loaghtan.
It's a rare breed that was a real treat to spin. I bought mine from Spirit Trail from whence so many wonderful woolly and unusual things come. it's an interesting primitive, and crimpy, a little dual coated, and delicious to say the least. 
So, a little question. Rare breeds. As a spinner or a knitter, do you try to use them? Do you think that helps sustain the breed? Is that something that interests you, or that you think about why you buy wool?
