I’m knitting socks with two straight needles from a King Cole pattern, leaflet: 4415 and having trouble with the heel shaping. The instructions are:K
I’ve got 24 sts on needle
1st row: K13, s1, K1, psso, K1 turn.
2nd row: P4, P2tog P1,turn.
3rd row: K5, s1, K1, psso, K1, turn.
4th row: P6, P2tog, P1, turn.
Cont as set dec 1 st on each row
K1, psso (13 sts)
Next Row: P11, P2tog, (12 sts) Slide remaining stitch from left hand needle to right hand needle. Break off yarn.
I’ve knitted the 4 rows twice which leaves with with 16sts, but when I follow the next instruction I am left with 15sts. Can you see what I’m doing wrong please.
