Cable needles are specialized knitting tools used to create cable stitches in knitting projects. They are typically short and have a slight curve or hook at one end, which helps hold stitches securely while you work. Cable needles come in various sizes to accommodate different yarn thicknesses and cable patterns. When knitting cables, you temporarily move stitches onto the cable needle, allowing you to knit other stitches before returning to the held stitches. This technique creates the twisted, textured patterns that are characteristic of cable knitting, adding visual interest to garments and accessories.
