Bo 4 sts on a RS row, continue across in the pattern st, turn.
BO 4 sts on a WS row, continue across in the pattern st, turn.
Now do the k3, skp on the RS row, work across in the pattern to the last 5 sts k2tog, k3. Then do a WS row, a RS row with no decs, a WS row, then do another dec rows - k3, skp, knit to last 5 sts, k2tog, k3.
What I meant about the decs was when you do the 3rd row that begins with the k3, you will have lost 5 sts at that point - 4 from the BO and 1 from the dec at the beginning of the row. So you can't start with the first st of the st pattern, you have to start it where stitch 5 would be. But it's much easier to look at your knitting and tell where you are than try and calculate it from the stitch pattern.
