4th row: Sl 1, *k1 winding the yarn around the needle 4 times, repeat from * to last st, K1 winding the yarn around the needle 3 times
5th row: Sl 1 dropping the extra wraps off the needle to make one elongated stitch, * slip the next 6sts to the right hand needle, dropping off the extra loops as you do so.
