Linda thanked me in the comments for offering a photo of a North Ronaldsay lock. I'd only shown one lock, and that's not the whole story by a long shot, so I'll supplement here. I have a selection of five different samples (thanks to Jennifer Heverly at Spirit Trail Fiberworks . . . one of my allies in this Massive Project I'm working on). Why and how they are different makes a fascinating story for another time.
Interesting, isn't it?
More or less double-coated, and dramatically so. The undercoats on the double-coated fleeces (the ones with the long, coarse guard hairs, second and fourth from either left or right) are similar to the fine fibers of the single-coated fleeces (first, third, and fifth, also from either direction).
So if you have been interested in North Ronaldsay and haven't been able to get your mind around the wool, this is why. The story is in the history of the breed.
I have another post to prep, on the Suffolk and the not-Suffolk discussion that started in March. So off to it. . . . Oh, and I have work to do today, too. I'm doing a week-long artist's residency through Colorado Art Ranch and need to make as much progress as possible during this time when I can actually concentrate.
