Using this Cascade 220 Superwash Wave yarn is a breeze. You can use it with standard knitting needles for a variety of projects like scarves, hats, or baby blankets. For crochet, it works well with medium - sized hooks. When it comes to care, since it's machine - washable, you can toss it in the washing machine on a gentle cycle with cold water. Use a mild detergent to keep the colors bright. After washing, lay it flat to dry to maintain its shape. Avoid wringing or twisting the yarn as it can cause it to lose its form. With proper care, this yarn will last through many knitting or crocheting projects and keep looking great.
