Using this Cascade 220 Superwash Wave yarn is a breeze. You can use it with your regular knitting or crocheting tools to create various items like scarves, hats, or baby blankets. When you're done with your project, you don't have to worry about delicate hand - washing. Just toss it in the washing machine on a gentle cycle and let it dry in the dryer. However, it's a good idea to use a mild detergent to keep the colors vibrant. Also, avoid using very high heat in the dryer to prevent any potential shrinkage. Store the yarn in a dry place away from direct sunlight to maintain its quality over time.
