Using these ChiaoGoo double pointed needles is a breeze. First, select the yarn you want to use. Thread it through the eye of the needle and start knitting as you normally would. When working on a project, make sure to keep the needles parallel to avoid uneven stitches. As you knit, the smooth tips will help the yarn move easily. When you're done knitting, gently remove the finished piece from the needles. To keep your needles in top condition, avoid dropping them on hard surfaces as it might damage the tips. You can clean them with a soft, dry cloth to maintain their satin - sheen finish. Store them in a safe place, like a knitting case, to prevent them from getting bent or lost. These needles are 100% recyclable, so when they reach the end of their life, recycle them properly.
