To knit cables you can cast on as many stitches as you want, as long as it’s an even number, so that the cable is centered.
Decide where you are going to place the cable. To knit this example, we cast on 12 stitches. Six stitches will be for the cable and on each side there will be 3 stitches.To not start with the crossed stitches we will knit 4 rows. Work the first 3 stitches in garter stitch (this means you will knit them), work the center 6 stitches in stockinette stitch, and work the last 3 in garter stitch.
