Using these Katrinkles stitch markers is a breeze. Just slip them onto your knitting or crochet needles at the spots where you need to mark. They're great for keeping track of your rows, patterns, or special points in your project. When using the acrylic markers, be careful not to drop them too hard as they might break. For the bamboo ones, avoid getting them too wet as this could damage the wood. To clean them, you can use a soft, dry cloth for both types. With proper care, these stitch markers will serve you well for many crafting sessions to come.
