Using these ChiaoGoo double pointed needles is a breeze. First, thread your yarn onto one of the needles. Then, start knitting your desired pattern as you normally would. When working in the round, use multiple needles to create a circular knitting setup. As you knit, the smooth tips will make it easy for the yarn to move. For maintenance, simply wipe the needles with a soft, dry cloth after each use to keep them clean. Avoid using abrasive materials that could scratch the satin - sheen finish. Store them in a safe place, like a knitting case, to prevent bending or damage. Also, since they're recyclable, you can dispose of them in an eco - friendly way when they're no longer usable.
