Using these Jimmy's SmartStix Double Pointed Needles is a breeze. Just pick up your yarn and start knitting as you normally would. The color - coded markings at one - inch intervals are great for measuring your work on the fly. To check your gauge, simply wrap the yarn around the needle and count the wraps per inch. When you're done knitting, make sure to store the needles in a dry place to prevent any damage to the aluminum. Avoid dropping the needles as it might bend them. If they get dirty, you can wipe them gently with a soft, dry cloth. That's all you need to know to enjoy your knitting with these awesome needles!
