I am very confused about a pattern I have. I am relatively new to knitting. This is my first sweater attempt. I feel like I am missing something. I am making a sweater vest. I am at the Armholes. The pattern shows:
Cast off 3 sets at beg of next 2 rows [143] sts. – I did this and have 143.
Dec 1 st at each end of next 5 rows, then on foll 7 alt rows. [119] sts.
This is where I am confused. I have 143, but the decreases do not reduce it from 143 to 119. That would be 24 stitches decreased. The instructions are for 5 + ?. I assume the 7 alternating gives me 7 decreases. That means 5 + 7 is only 12, not 24.
What am I missing on this?
