help with sweater please

if i am not following a pattern, how do i know how many stitches to decrease for the armhole shaping

should i get a pullover i already have and measure the armhole then multiplye that number with the number of stitches per inch or what? i have a feeling that this is not correct at all haha :smile:
your help is appreciated.

That sounds like a great idea. If you have a sweater already with a fit similar to the one you’re making, it’ll give you a good estimate of the length of the bind off for the armhole.
If you’re knitting this as one piece (in the round) then you’ll use the full measurement. If you’re knitting separate front and back then it’ll be about half the measurement and you should take into account a stitch on each piece for seams.

well thank you very much!:blush:
