Using this Cascade 220 Superwash Wave yarn is a breeze. You can use it with your regular knitting needles for all your knitting projects. For crocheting, pick the appropriate hook size. When it comes to cleaning, just throw it in the washing machine on a gentle cycle and let it dry in the dryer. However, be careful not to use extremely high heat as it might damage the yarn. If you notice any loose ends, simply tie them off neatly. Store the yarn in a cool, dry place away from direct sunlight to keep its colors vibrant and the yarn in good condition.
