A merino worsted weight yarn. It is soft and bouncy, and good for everything that doesn't need to be washed in the washing machine. It's terrific for sweaters, because it shouldn't stretch out and it dyes beautifully in our tonal colors, plus it's less expensive than our Superwash Merino.
4-5 sts/inch, size 7-8 needle.
