Spinning
There is so much info on the web about spinning that having anything more than a few paragraphs here seems pointless!
WeatherWool requires two types of spinning: worsted spinning and woolen spinning. The machinery to spin each is significantly different, which is why our worsted spinning is done by Kentwool Yarns and our woolen spinning is by American Woolen.
Kentwool spins our warp yarn. The warp yarn runs lengthwise through a bolt of fabric. The weft yarn runs crosswise through a bolt of fabric. The weft is very fuzzy and thick (woolen-spun) and the warp is thin and slick (worsted-spun). In general, the weft provides the characteristics of the fabric, but our MidWeight Fabric is (by weight) 31% warp, and our FullWeight is 21% warp. So the performance of the warp is a major component of the performance of our Fabric, and this is why we go to the trouble and expense of 100% wool warp. Many "woolens" will use warp made of other materials. But ... that's "weaving" and this page is "spinning"!!
As usual, Woolmark, the great Australian wool trade-promotion organization, has a terrific 3-minute video with an overview of wool processing, including spinning and preparation for spinning. We do take one exception to this video, however. Woolmark mentions that shorter fibers go to woolen spinning and longer fibers to worsted spinning. All our fiber is long, suitable for worsted spinning. We use exceptionally long fibers because this will make stronger yarn, and therefore stronger and more-durable garments. Yarns made from longer fiber will also be more comfortable against bare skin. As usual, this approach is more costly!
Wikipedia has a substantial entry on spinning, and as usual it is cross-linked to many other entries with more information!

Below is some basic information (in the form of a first draft-email of 28 January 2023) about spinning from Advisor Rob Stuart, who has been working with us since we began to develop Fabric!
