Using these ChiaoGoo double pointed needles is a breeze. Just thread your yarn through the eye of the needle and start knitting your favorite patterns. When using, make sure to hold the needles gently but firmly to keep your stitches even. As for care, avoid dropping them on hard surfaces to prevent bending. After each use, wipe them clean with a soft cloth to keep that smooth finish. Store them in a knitting case to protect them from damage. If they get dirty, you can wash them with mild soap and water, then dry them thoroughly before storing.
