Using these ChiaoGoo Knit RED Circular Needles is a breeze. First, choose the right size and length for your project. Then, simply thread your yarn through the cable and start knitting. When using, avoid pulling the yarn too hard as it might damage the nylon coating on the cable. To clean the needles, use a soft cloth to wipe them down. You can also lightly polish the stainless - steel parts to keep them shiny. Store them in a dry place to prevent rusting. With proper care, these needles will serve you well for many knitting projects.
