Shelby looks to be part Border Collie. We can't be sure, she was a "mixed breed" puppy (Shelby doesn't care for the word "mongrel"). We bought her from the SPCA who had rescued her from a backyard full of miscellaneous interbreeding canines. If her tendency to herd roving is any indication, I would think that somewhere in the line her forefathers did include some breed of herding dog. When I put this wool roving down to take a picture she circled and sniffed, circled and sniffed. Having tasted wool in the past she resisted the urge to nip at its flanks.
I have now completely spun up and plyed the Coopworth Top that I started with. I haven't yet decided what to do with it. This new stuff, a hand dyed roving, is proving much more difficult to work with. The fibers don't slide apart as easily and my resulting yarn is thicker and uneven. Kind of discouraging when I was doing so well with the top.
