Summer is meant for cool, breathable knits! Iris is a worsted weight yarn that is a divine blend of cotton, bamboo, Merino wool & yak. With a hand similar to a favorite cotton t-shirt, the yarn feels so comfortable against skin. The beautiful drape & chainette construction is perfect for summery tees, tops, tanks & wraps. A touch of yak fiber gives each colorway a subtle heathered look.
