My other nephew, Big Foot's twin, wears a size 13 - which is interesting because a number of men in my life have size 13 feet.
So, here's a sock I made for him last night:
Yarn: Knit Picks Pallet
Hem: Plain hung hem - 20 cranks
Leg: 30 rows
Foot: 78 rows
Gage: 8 sts/9 rows per inch
Toe to Heel measurement: 12 inches
