V neck - where did I go wrong?

Hello everyone

I’m knitting a simple ribbed V-neck

and I’m sure I’ve gone wrong in the shaping :

[I]Shape Right Front
Row 1 (WS): Work in Rib across 51 (57, 63, 69, 75) sts only, slip rem 42 (48, 54, 60, 66) sts onto a stitch holder.
Row 2 (neck dec row – RS): K3, p3, k3, p2tog, work in Rib to end.
Rep last row (neck dec) every 4 rows 17 more times, AT THE SAME TIME, when piece measures 12 (13, 14, 15, 16) in. (30.5 (33, 35.5, 38, 40.5) cm) from beg, end with a RS row and shape armhole as follows: [/I]

I read the pattern to mean I should begin shaping the V by repeating [WS RS WS dec] 17 times before starting to shape the armhole. From the photo, I could see the V began below the armhole so this made sense. However, after 10 blocks of 4 rows I can see the V is WAY too deep. How should I have read the pattern please?

Sandra (learning by her mistakes!)

You won’t get all 17 decreases done before you start the armhole shaping. Keep an eye on the overall length from the beginning - when the piece is the right length (see bold above) that’s when you start the armhole shaping. From then on, you’ll be doing the arm shaping and the v-neck shaping at the same time.

Yep, start the armhole shaping when the length of the whole piece is 12, 13, 14 whatever inches from the cast on, not from where you start the V.

Thanks Marilyn and Sue - I will have to take some rows back and hopefully manage to pick up the stitches. If not I’ll start over, it’s all good practice!
