Using these ChiaoGoo RED Lace Circular Needles is a breeze. Start by choosing the right size and length for your project. Simply thread your yarn through the cable and onto the needle tip. As you knit, enjoy the smooth glide of the yarn across the needle and cable. When you're done, carefully remove the finished piece from the needles. To keep your needles in top condition, avoid bending them forcefully. Store them in a dry place away from sharp objects to prevent scratches. And remember, the US 17 size has a non - standard measurement, so be aware of that when planning your project.
