Magic! Berroco Sox yarn creates the pattern for you while you knit! Fabulous print patterns and colorways give this sock yarn the edge! It knits up beautifully on US 2 (2.75mm) needles, and is machine washable thanks to its 75% superwash wool! One ball will knit a pair of adult socks, and nylon is added to ensure they keep their shape! The fabulous print shades are beautifully blended; you'll be knitting a pair in each color!
