Enjoy smooth and hassle-free knitting! With this Knitting Ferrule Yarn Guide, it controls yarn tension and prevents tangling. Keeps wool and yarn out of the way while knitting. Thanks to the holes in the top of the ferrules, up to four wool threads can slide gently over the knitting pin and prevent the wool threads from tangling and knotting. Work neatly with multiple strands of yarn. The latch on the eyelet can be opened and slid very easily to change the color sequence while knitting. Even intricate Norwegian patterns and all kinds of multicolored patterns can be achieved perfectly and easily. OUR GUARANTEE We are confident that we offer some of the best products on the market.
