Using this Cascade 220 Superwash Wave yarn is a breeze. You can use it with regular knitting needles or crochet hooks to create all sorts of items like scarves, hats, or baby blankets. When it comes to maintenance, since it's machine - washable, you can toss it in the washing machine on a gentle cycle with mild detergent. Then, you can put it in the dryer on a low - heat setting. Just be careful not to use hot water or high - heat drying as it might damage the yarn. Also, if you're making a garment, it's a good idea to block it after knitting to give it a nice shape. Enjoy creating with this wonderful yarn!
