Tailored knitting stitch pattern with chart. Just knits & purls - 15 row repeat. Alternate rows knit as indicated. Very easy, but this is a pattern you must watch while you knit. Not a knit while watching TV pattern. Would be great for throw or blanket.
i think you could make this with tunisian. when it gets the the split, you could keep working half the stitches until both halves are long enough and then start stitching across the entire piece again at the other end.
