Sweater/tank question

just wondering if many of the sweater patterns I see could actually be done sleeveless (by not adding them) and would there be anything specific you would have to do to finish the armholes or does it depend upon the pattern?

I would say that most of the time, if you like where the sleeves start as a look for you tank, then akll you would have to do is knit or crochet a round the openings. Most sweaters use a decrease method that does not leave a flawless edge, you know?

Thanks, it seemed to make sense but since I’ve not yet attempted a sweater, I thought this might ease me into it. And I rarely need long sleeved sweaters even in winter here.
