Mey Seacell Sock Yarn is 70% superwash merino and 30% seacell. It is a beautiful 2 ply sock yarn with a generous 368 yards in every skein. This yarn is hand-dyed in small lots consisting of only two or three skeins per dye session. This yarn is machine washable, but in order to extend the knitted item’s life, air dry them flat.
