For my homework for this class, Sandi let us spin whatever fiber & fiber prep we wanted, but it had to come out a 2-ply fingering weight. For this, I chose 2 ounces (~56 grams) of pure cashmere.
(Looks like a cloud, doesn't it?)
It was lovely, it was soft, and it spun like an absolute dream. When it came off the wheel, it was absolutely perfect -- slightly over twisted in the plying. Woolen-spun yarns tend to lose twist, so overplying by a little bit is a good thing here! I ended up with 160 yards.
After washing and fulling it, it came out nearly balanced with a slight over twist. Perfect!
Folks in class brought their homework for show & tell. There was plenty of lovely fibers; one student had such a stressful week that she managed to spin up vicuna, camel, cashmere, cotton silk, and a whole slew of other sampler skeins as her relaxation!
But for class, we primarily spun more fiber; I got to spin up a little bit of bison, while another student attempted some dog hair.
Bison is also a short staple length fiber, but I found it slightly harder than cashmere to spin. The fiber is not completely uniform in length --- bison are not bred for fiber -- so the fiber looks more "rustic". But, it's nearly as soft as cashmere (and just as warm).
The finished skein is lovely. I washed and fulled it slightly for a nice halo effect. It's also about a heavy fingering weight.
