What's chunky and made of 100% superwash Merino wool? Chunky Merino Superwash by Ella Rae fits the description. This bulky weight yarn is super-soft and springy, maintaining its loft even after machine-washing. Each 3.5 ounce (100 grams) 136 yards (124 meters) skein is quick to knit and a great basic yarn to keep on hand for fast projects.
