Using these KnitPro Mindful Collection Fixed Circular Needles is easy. Start by threading your yarn through the cable. They're great for both lace knitting and regular projects. When knitting, the inch - marked cable can help you measure your work. Be careful not to bend the needles too much as it might affect their shape. To keep them in good condition, store them in a dry place. After use, you can gently wipe them with a soft cloth. If you notice any dirt on the cable, a mild soap and water solution can be used for cleaning, but make sure to dry them thoroughly.
