The pattern will begin to repeat after approximately 55 rounds of a normal, adult-sized sock. That will of course vary based on your gauge, the circumference of the sock, etc.
You will receive TWO 50-gram skeins, 231y per skein, matched to the stitch. No more fishing around trying to find the place to start the second sock!
75% superwash merino, 25% nylon, fingering weight.
