The Yarn Guide makes yarn management a breeze! Made of soft, lightweight, durable plastic, this handy Yarn Guide from Clover fits comfortably on the finger. It is incredibly helpful while knitting with two or more different yarns. It helps to keep your tension or while working with multiple strands of yarn. Instructions: Insert the index finger into the Yarn Guide. Flip the top open and place the yarns between the guides and snap it close over the yarn.
