Using these ChiaoGoo Knit RED Circular Needles is easy. Just thread your yarn through the cable and start knitting as you normally would. When choosing a needle, pick the size and length that suits your project. For larger projects, longer needles may be more comfortable. Be careful not to bend the cable too sharply, as it might damage the nylon coating. After use, gently wipe the needles with a soft cloth to keep them clean. Store them in a dry place to prevent rusting. These needles are tough, but avoid using them on very abrasive yarns that could scratch the surface.
