Using these ChiaoGoo double pointed needles is a breeze. Start by choosing the right yarn for your project and thread it onto the needle. Begin knitting as you normally would, and the tapered tips will help the yarn move easily. When you're done with your knitting, make sure to store the needles in a dry place to prevent rusting. If they get dirty, you can simply wipe them with a soft, dry cloth. Avoid using harsh chemicals as they may damage the satin - sheen finish. And don't forget, since they're recyclable, when it's time to part ways with them, you can do so in an environmentally - friendly way.
