Using these knitting needle sets is easy. First, pick the right set for your project. If you're making small items like socks, the DPN sets (like the Gracious set with US 0 - 3 needles) are perfect. For larger projects like scarves or blankets, you might want to use the circular needle sets. When using the cables, just thread your yarn through and start knitting. The marked cables can help you measure your work as you go. Remember, the cables won't kink or curl, so you don't have to worry about that. Keep the accessories in the detachable pouch for easy storage. As for maintenance, after each use, wipe the needles with a clean, dry cloth to keep them in good condition. Store the sets in a cool, dry place to prevent any rusting on the stainless - steel parts. Also, be careful with the stitch markers as they're small and can be easily lost. And don't forget, if you ordered this product and it comes in a KnitPro package, that's just part of the brand transition.
