From the Trendsetter Yarns website:

New from the Lane Borgosesia collection, this really fun yarn is similar to Tonalita but is about twice the thickness and additional flecks of color are added by small viscose pieces being injected during the spinning process. the yardage is great… this is a no brainer!!!
52% pure virgin wool/44% acrylic/4% viscose
