Shaping Sleeve Conundrum

I’m having a bit of trouble understanding part of a pattern and hoping some of you could help me :slight_smile:

The pattern reads (for a puffed sleeve cardi currently knitting the back of the work bottom to neck)

[B]Shape Armholes[/B]
[I]Keeping stripes correct, cast of 3 sts at beg of next 2 rows. 61 sts.
Dec 1 st at each end of next 3 rows, [U]then on foll 2 alt rows. 51 sts.[/U][/I]

The part I’m stuck at is underlined. To my mind, if I dec 1 stitch every 2nd row, then one side will be ‘lop sided’ wouldn’t it?

Thanks in advance!

Knitting Newbie :knitting:

You should decrease 1 st at each end of next 3 rows, and then [U]dec 1 st at each end[/U] of the foll 2 alt rows. That way the back will be symmetrical as you thought and you’ll be decreasing 10 sts total which is consistent with the change in total sts from 61 to 51sts.
Enjoy knitting your sweater!

It says to dec [I]each[/I] end of the next 3 rows, AND then on every other row twice.
