We had one summer-like day and I got to sit outside spinning on the porch. This is the Merino superwash I bought last year before the house was finished. The spindle is as Ashford. I'm not sure if it's the 1 oz. or 3 oz. size. I'm looking at more spindles and a wheel purchase soon.
Here's the Merino plied. I wound a center-pull ball tightly so as to maintain the tension. Then I held the two ends together and wound them around the spindle shaft to start the plying.
Mohair feels different from sheep's wool; more like hair, which I guess it is.
