i want to learn how to knit but i'm not sure where to begin. i've never done it

i feel like i want to get big knitting needles and really chunky yarn and make a blanket. would that be too big of a project to start on? tbh i don't want to knit scarves or any clothes because i know they'd probably turn out ugly and i'd never wear them. i just want a big chunky knitted blanket and i feel like it'd be simple if i just do a square one but idk. does anyone have any advice? how hard is it to learn to knit? what materials should i buy to start with?
