Using these KnitPro Mindful lace needle tips is easy. First, choose the cable you want. Remember, all tips can be screwed onto all cable sizes, but for a 16 or 20 needle setup, use the 4 tips. You can pick a swivel or non - swivel cable based on how you like to knit. When you're done knitting, gently clean the needle tips with a soft cloth to keep them in good condition. Since they're stainless steel, they're durable, but try not to drop them hard as it might damage the tips. Store them in a dry place to prevent rusting. And don't worry if your product comes in a KnitPro package; it's the same great - quality tool you're expecting.
