You can make socks with any yarn. Worsted weight makes really thick socks, fingering makes socks you can wear in shoes, dk and sport yarn are in between. You can use any fiber. Maybe you should check patterns, find some you like and see what yarn they recommend.
Cheating is an option. . . . Cheaters never win and winners never cheat, but smart knitters who want to retain an iota of sanity do, cheerfully. ~~Kory Stamper
