Here's the most recently finished pair, in an unknown worsted weight wool that was gifted to me. Basic sock, CO 24 on size 4US. Knit 12 rounds. Knit 12 rows in the heel flap. After heel turn and picked up stitches, decreased back to 24 sts. Worked even until it looked long enough, then decreased for toe down to 8 sts total. Grafted toe.
