WT Worsted is an organic, non-superwash merino 4 ply yarn that is known for its unique qualities. Because of its non-superwash nature, it will felt if washed and dried in laundry machines, so it is highly recommended to hand wash in cold water and dry it flat to preserve its integrity. Organic yarns tend to have more muted colors than their superwash counterparts, but I have dedicated significant effort to create a beautiful range of richly saturated colors that stand out and bring life to your projects.
