There are 2 corrections for the alternate, larger calf version of the sock.Rows 33A and 38 A are missing the term “blo”. They should read as follows:
Row 33A (short Row) (alternate larger calf version): Ch 2, hdc blo in each of first 30 sts, sc blo in each of the next 10 sts, ch 1, turn, sc blo in each of the first 10 sts, hdc blo in each of the next 30 sts, ending at the calf edge.
Row 38A (short Row) (alternate larger calf version): Ch 2, hdc blo in each of first 30 sts, sc blo in each of the next 10 sts, ch 1, turn, sc blo in each of the first 10 sts, hdc blo in each of the next 30 sts, ending at the calf edge.

When you climb up that giant beanstalk, you’re gonna want a nice comfortable pair of socks with a reinforced (but stretchy) toe and heel. They’ll keep your feet warm at high elevations, but they’re pretty enough to wear to dinner at the Giant’s castle.
