Spinning 8 oz of corriedale with a spindle takes a long time. At least it has for me. The balls are the plying balls ready for plying. I spun up the singles with the intent of making a 3-ply yarn. The larger ball is what I most recently spun up. The singles gave me a lot of trouble when wrapping the plying ball because one of the singles kept breaking. This is when I learned to do spit splicing, but I can't say I love that technique.
