Using these ChiaoGoo double pointed needles is a breeze. Start by threading your yarn onto one of the needles. Then, you can begin knitting your desired pattern as you would with any other knitting needles. When it comes to care, avoid using abrasive materials that could scratch the satin - sheen finish. After each use, simply wipe the needles clean with a soft, dry cloth. Store them in a safe place, like a knitting case, to prevent bending or damage. These needles are made of surgical - grade stainless steel, so they're very strong, but still handle them with care. Enjoy your knitting with these high - quality needles!
