Cables are knitting structures that can create expressive textures and patterns on a given project. They are created by knitting your stitches out of order - partially creating one set of stitches, then moving on to another set, then returning to complete your previous set. The result of this back and forth process is that the stitches literally cross over and twist around each other; this fundamental concept can be used to produce extremely ornate motifs. You'll need a cabling needle in addition to your regular knitting needles in order to start getting into this technique. Cabling needles are smaller needles that simply hold your stitches together as you put them aside, preventing your project from unraveling as you begin creating cables.
