Using these ChiaoGoo Mini [M] Cable Connectors is a breeze. First, make sure you have the right [M] coded cables. If you're in the middle of a project and need a longer cord, simply take two [M] coded ChiaGoo Twist Red Cables of the same size. Attach the connector to one end of each cable, and you'll have a longer cord for your project. When it comes to storage, keep them in a dry place away from sharp objects to avoid damage. Always double - check that the connector fits snugly onto the cable before starting your knitting to prevent any issues during your project.
