I used the yarn sink for the first time this afternoon. I had half a pound of Cherry Tree Hill Roving that I spun and finished plying last night. There was plenty of room in the sink for all the yarn. To speed up getting hot water to the sink I started a load of hot water wash first. There is some multi tasking that is good. I like using soak when I wash my hand spun yarn. I will have to come up with another method of thwacking the yarn. I am afraid it made the whole sink shake and I was worried that I might break the sink. Too bad they did not have a cast iron sink for a laundry sink. Check with your local yarn shop or Raverly to get some Soak.
