It was this partnership with a woolen mill that brought Koigu's Premium Merino yarn into existence. The yarn is light, so it can be worn indoors and out, soft, so it can be worn next to the skin, and of course, 100% merino. In an age when thicker yarns that yield quicker results were all the rage, KPPPM was an anomaly. An anomaly that everyone had to have. Koigu's signature yarn became legendary, known for its wearability, its versatility, and above all, the stunning colorways.
