I am taking a class on breed specific wool on craftsy. It is really fun and FREE. What has been eye opening for me is the differences from one breed to another. For my swatches of the breed yarns I am knitting.. But I might also try some rectangular woven swatches, at least with the Jacob. This breed of sheep are so beautiful. Here is a picture of the natural yarn
Below is a knitted swatch of Cormo. I got this from elsawool and have s skein of woolen spun and worsted spun yarn. This spinning has nothing to do with the worsted weight..that is a separate quality. What a difference in the two types of yarn. The woolen spun is fluffy and springy whereas the worsted spun is silky and smooth. I think for continuous strand weaving I prefer woolen spun yarn... I will swatch the worsted spun just to be sure.
