ChiaoGoo connectors allow you to link two interchangeable cables together, extending the length of your circular needles to suit your project's needs. They are ideal for larger projects like shawls or blankets. No need to transfer your stitches to another cable or a support thread: simply unscrew one end , connect a new cable using the connector, and you're done. These handy accessories also allow you to adjust the cable length as you knit , as your project progresses.
