I’ve done steeks and they’re not as scary as they sound. They are extra stitches that you knit and later cut so you can knit all the way up a sweater in the round. You make steek stitches for the armholes and sometimes for the neck shaping. You can also do a cardigan in the round with steek stitches up the front opening, which you cut open later for the front of the sweater.
