This 50g ball of polyester knitting yarn is perfect for DIY projects like baby scarves and hats. To use it, simply pick up your 5.0 - 6.0mm stick needle or 4.5 - 5.5mm crochet hook. Start knitting or crocheting as you normally would. Since it's 100% polyester, it has anti - UV features. When you're done with your project, to maintain it, you can hand - wash it in cool water. Avoid using harsh detergents. Also, don't wring it out too hard to keep its shape. Just gently squeeze out the water and lay it flat to dry. Store the extra yarn in a cool, dry place away from direct sunlight to preserve its quality.
