Using these Jimmy's SmartStix Double Pointed Needles is a breeze. Start by choosing the right size needle for your project. The color - coding makes it easy to keep track of measurements while you knit. Just align the needle with your work to measure as you go. When it comes to care, simply wipe the aluminum needles with a dry cloth after use to keep them clean. Avoid using harsh chemicals as they can damage the finish. Store them in a dry place to prevent rusting. These needles are lightweight, so be careful not to misplace them. And remember, they're a unique tool, so make the most of the built - in ruler feature for accurate knitting!
