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 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!). Or, use the same needles but use the pattern numbers for the 8” foot size (largest child size), but go up a needle size for the stranded parts.
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 decr to 52 After colorwork, decreased to 44 and followed pattern for the 8” sock worked 12 r before starting heel worked 15 heel rows 55 rows from heel to start of toe decreases (7”)
