Cotton and wool are two natural fibers with their own amazing properties—when the two are combined, the result is a wonderfully unique blend with all the advantages of each fiber. Cotton Fleece is spun with 80% pima cotton and 20% merino wool. It derives its strength and coolness from cotton, along with memory, bounce, and a touch of warmth from the wool. Cotton Fleece is cool enough to wear in any season, making it our most popular yarn for crocheters and knitters who live in warm climates. Cotton Fleece is easy to care for, making it a great choice for children’s and babies’ knits.
