It was a busy time when these were done which is why it took me 6 months to spin and knit. I’d say my total time was 12 hours +/- 2-3.
I wish I had made the cuff a little longer but I was running out of yarn.
Used toe up method on 60 needles. Plain knitting to heel. Used 1 up, 2 down method on heel. 15 rows above heel, switched to ribber and cast off from the top of ribbing.
