Using these Jimmy's SmartStix Double Pointed Needles is a breeze. Start by choosing the right needle for your project. The color - coding at one - inch intervals is a great help for measuring as you knit. To measure your gauge, simply wrap your yarn around the needle and count the wraps per inch. When you're done knitting, make sure to keep the needles in a safe place to avoid bending or losing them. Since they're made of aluminum, they're lightweight but still need gentle handling. You can clean them with a soft, dry cloth to keep them in good condition. That's all you need to know to make the most of these handy needles!
