We purchased this single ply linen yarn as a remainder lot.
This is a 9 lea single ply linen yarn. For Linen, the count system is based on size called a lea. One lea is the size of a yarn spun to 300 yards from 1 pound of linen flax. Typically, linen yarns are numbered with the same nomenclature as cotton yarns, with the yarn size first and the ply number second. Thus, This yarn would be a 9/1 linen yarn.
