You're going to work extra rows on just the stitches on needle 1, every 3 rounds. So knit those sts and turn as if you were working flat and turn at the end of the row. Work on the WS and turn again, then go over them again and continue on around the rest of the stitches. Work 2 more complete rounds on all the sts, then on the stitches from needle 1, turn and do a WS row, then complete the round. These are 'short rows' and are used for shaping, to add some extra room in that section.
