I ended up just adding more rounds of garter stitch at the cuff. They're a bit small for my big feet but not too small that I can't wear them. I have them on now, they feel so nice. The 2nd photo is to show how tightly they're knit. They can stand up by themselves.
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
