Cable stitch is a type of knitting stitch that creates a textured, twisted pattern resembling cables or braids. It is formed by crossing groups of stitches over each other, which gives the fabric a three-dimensional, braided appearance. Cable stitches are commonly used in knitting to add visual interest and depth to garments, such as sweaters, scarves, and hats. The technique involves using a cable needle to temporarily hold stitches while crossing them over to create the cable effect.
