Hayfield Spirit Chunky, a Sirdar yarn that is 20% wool and 80% acrylic is washable and perfect for blankets, sweaters and accessories. Each skein is 169 yards and recommended hook size is K or 10.5 needles. Four of the skeins are unopened with labels. I also have two other balls, both of which are almost full but I rewound them and do not have the labels . The color combo is beautiful variegated blues with white. There are two different lot numbers on the labels but I cannot tell any of the skeins apart. All are Shade 402. This is a nice, chunky but soft yarn that will work well on numerous projects.
