This pattern uses one long circular to knit sweatpants-style pants with faux cable accents and racing stripes down the sides of each leg. You will knit both legs simultaneously no seams, no grafting! It comes in four sizes to fit your child x-small to potty training. Peace Fleece worsted weight yarn is recommended for all of the patterns in the Faux Cable Collection. I’ve included instructions for customizing the pattern for the hard-to-fit baby.
