As you knit, move the stitches from one needle to another. To keep your needles in top shape, avoid dropping them on hard surfaces as it might damage the tips. After use, simply wipe them clean with a soft cloth. You can store them in a knitting needle case to prevent them from getting bent or lost. If you notice any dirt or debris on the needles, you can gently wash them with mild soap and water, then dry them thoroughly before storing.
