Using these Jimmy's SmartStix Double Pointed Needles is a breeze. Start by choosing the right color - coded needle according to your project. You can use the one - inch color - coded intervals to measure your knitting as you go, helping you keep track of size and gauge. When you're done knitting, gently clean the needles with a soft, dry cloth to remove any lint or debris. Store them in a dry place to prevent rusting. Avoid using these needles for projects that require excessive force as they are made of lightweight aluminum. And always keep them out of reach of small children to avoid any potential hazards.
