Smock pattern knitted

By smocking you create a raised diamond pattern.
On our sample we cast on 22 sts. We work with multiples of 3 + 1.
row 1 RS: K1, *P2, K1*, repeat *-* when 3 sts remain P2, K1.
row 2 WS: K1, *K2, P1*, repeat *-* when 3 sts remain K2, K1.
Repeat row 1-2 for rib pattern.
1st smock row, work next row from RS:
K1, *P2, stick in the needle after next 4 sts, after 2nd K st, pick up the yarn, place loop on left needle, K loop and first st tog, P2, K1*, repeat *-* when 3 sts remain P2, K1. Work 5 rows in rib as before.
2nd smock row, work next row from RS:
* stick in the needle after next 4 sts, after 2nd K st, pick up the yarn, place loop on left needle, K loop and first st tog, P2, K1, P2*, repeat *-* when 4 sts remain: pick up the yarn after the last 4 sts, place loop on left needle, K loop and first st tog, P2, K1. Work 5 rows in rib as before. Repeat smocking rows alternately on every 6th row.
