I have been knitting a jumper but have come to a section of the knitting pattern that I am struggling to understand. The pattern says:
1st row - (RS) K2, sl 1, K1, psso, K12 (17-21-24) turn.
Cont on these 15 (20-24-27) sts, for left side of neck shaping.
Dec one st at armhole edge (as before) in foll alt rows 1 (7-13-16) times, Sizes S and
M Only - then in foll 4th rows 4 (2) times,
All Sizes - AT SAME TIME dec one st at neck edge in foll alt rows 7 (7-5-2) times, then in foll 4th rows 1 (2-4-7) times … 2 sts.
I do not understand where it says turn, cont, foll 4th rows or foll alt rows.
Here is the link to the pattern:
Some help from an experienced knitter would greatly be appreciated.
