A cable needle is a specialized tool used in knitting, particularly for creating cable patterns. It is typically a short, curved needle that helps hold stitches in place while the knitter works on other stitches. This allows for the intricate twisting and braiding of yarn that characterizes cable designs. Cable needles come in various sizes and materials, including metal, plastic, and wood. They are essential for knitters who want to add texture and complexity to their projects, making them a popular choice among those who enjoy working with yarn and knitting needles.
