Using this Cascade 220 Superwash Wave yarn is a breeze. You can use it with your regular knitting or crochet needles for various projects like scarves, hats, or baby blankets. When it comes to maintenance, you're in luck! Just throw it in the washing machine on a gentle cycle and let it tumble dry. This will keep the yarn looking great for a long time. One thing to note is that although it's machine - washable, avoid using harsh detergents as they might fade the beautiful colors. Also, don't wring the yarn forcefully when it's wet to prevent any damage. Have fun creating with this wonderful yarn!
