Using these KnitPro Mindful Double Point Needles is easy. Start by choosing the yarn you like. Thread the yarn through the tip of one needle and begin casting on stitches. When knitting, you can move the stitches from one needle to another. These needles are great for small, circular projects like socks, hats, and sleeves. As for maintenance, keep them in a dry place to prevent rusting. And remember, although the brand name and packaging have changed, the quality of these needles is still top - notch. Just handle them gently to ensure they last a long time.
