OK, so the directions become:
Shape front neck
Keeping stripes correct, cont as follows:
next row (rs) (K2tog) 1] time, K11 and
turn, leaving rem 8 sts on a holder (for Neckband).
12 sts total. Turn as you would at the end of a row. Ignore the unworked sts for the moment.

at same time dec 1 st at raglan armhole edge of 2nd and foll
3 alt rows. 2 st remain. Dec 1 stitch at the neck edge on rows 1,2,3 and 4, then on rows 6 and 8. Dec 1 stitch at the armhole edge on rows 2,4,6 and 8.
