Tightening Up Cable Edge Stitch Tutorial
Frequently knitters have problems with the left edge of their cable stitch being very loose. The main reason for this is the purl stitch that follows the cable. Purl stitches use more yarn which allows the excess yarn to slip into the knit stitch next to it. I find that wrapping the purl stitch 'backwards' really helps tighten and tidy up that edge of my cable.
