i almost never do the same thing twice!
but i have 2 times, ribbed the back of the stock (with the ribbing in V pattern (starting center back and ever few rounds more and more ribbing, until all the stitches in back are ribbed)
once i just ribbed the back, most recently, i started ribbing in back, then continued ribbing (in a straight line) to front, and ribbed all the way round.
but i don't always rib top edge of the sock... (and sometimes i do 1 X1, and other times 2 X 2, and sometimes do 3X1)
for me the fun of socks is making each pair different!
