As an avid knitter, I can confirm it really is. In practice there might be multiple knots as you change balls of yarn for example but topologically each sweater is just a very fancy knot. In fact, the words are etymologically linked, they’re really just the same word! See https://www.etymonline.com/word/knit https://www.etymonline.com/word/knit > knit(v.) > Old English cnyttan "to tie with a knot, bind together, fasten by tying," related to Old Norse knytja "bind together, form into a knot," Middle Low German knütten "to tie, knot," Old English cnotta "a knot," from Proto-Germanic knuttjan, from stem knutt-. Of brows, late 14c. Intransitive meaning "do knitting, weave by looping or knotting a continuous thread" (especially in reference to plain stitch) is from 1520s.
