Just before Rnd 3 (which will become the first *real* round), there is a note: "Complete neckline and join front neck with additional sts." This is what those 9 BASE CH/SC sts are for. After you make them, sl st in the top of the Ch3 you made at the beginning of this round, then fasten off...
I am trying to do the jewel sweater, and I am stumped. I can't figure out what to do with that chain base/single crochet 9!! I agree that the directions are not very clear. Can you give me any suggestions or hints for the neckline?
