Using these ChiaoGoo Knit RED Circular Needles is easy. Just start by threading your yarn onto the needle and begin your knitting stitches as usual. The smooth nylon - coated cable makes it a breeze for the yarn to move. When you're done with your project, simply unthread the yarn. To keep your needles in good condition, avoid bending them too much as they're made of steel. Also, store them in a dry place to prevent rust. If they get dirty, you can gently wipe them with a soft, dry cloth. That's all you need to know to enjoy knitting with these great needles!
