hi im struggling with this pattern: at the end of the first page i should have 48 stitches, shape armholes i cast off 11 stitches at beginning of next two rows leaving me with 26 stitches the problem is when i get to ‘shape Left Neck’ know 15 stitches, turn and slip remaining 33 stitches??? to holder - i don’t have 33 stitches! please help

Thank you

You’ve knit the back of the sweater and at 9 1/2 inches, cast off 11sts for the shoulder. On the left front you work as for the back but only up to 5 1/2 inches. You’re not up to the shoulder cast off of 11sts yet.
The front neck shaping begins at 5 1/2 inches. At this point you should have 48sts. Knit 15sts, turn and place remaining 33sts on a holder.

Thank you, so when i get to the front part do i cast on 52 stitches and follow back instructions?

Yes, follow the back instructions but when the armhole is 5 1/2 inches, follow the instructions for the front.
