I already had it unraveled twice… !

Better result with a larger needle size.

1. Cast on 120 st & work in the round until 6½ inches. From now work only forth & back the last 60 stitches of the back; until back measures 10’. Work 17 st in pattern; 26 st in garter; 17 st in pattern for 5 rows Bind of the 26 central st. Go on on 17 st and make front yokes top/down Knit together each stitch of left yoke with each stitch of right yoke Sew the 2 yokes with the waiting 60 front sts with mattress stitch.

2. The long sleeves are too short : they should measure 8’ to fit the others measurements that are approximatively those of a 3 months aged baby. I decreased every 8 rounds instead of 6.
