With the US4 needles, the stranded colorwork part was the right size, but the rest of the sock was way too big. Decreased an extra 4 sts after the colorwork. This will be fine for house socks, but it’s still slightly bigger than I’d like. Would use smaller needles next time for everything but the stranded parts (and switch to the smaller needles for the plain rows in the colorwork section as well!).
My gauge was way off - on the US4 stockinette sections, it was 21.5 st and 30 r over 4”.
Cast on 56
worked rib for 11 r

After colorwork, decr to 44

55 rows from heel to start of toe decreases (7”)
