This yarn has a different fiber content than the Light Sport weight sold in hanks and on cones.
From the Beaverslide website:
We have just received our 14 selections in 2-ply sport/sock weight mule spun yarn. This yarn is a balanced 2-ply in a lighter weight than our worsted. It knits up at approximately 6 st./inch on size 1-3 needles. The skeins weigh 4 oz. and there are a generous 458 yds. per skein.
An assortment of dyed and natural choices are available, and we are quite please with the quality and feel of these new yarn selections.
