The sock is knitted cuff-down. A very easy and quick pattern. Pattern can be used for male or female socks.
You can use any sock yarn you like. But with semi solid or solid yarn the pattern shows best.

Update 12-2-2014 There was error in the heel turn of the largest size.
Should be: Row 2: (RS) sl1, k(3/3/5), ssk, k1, turn.

The German translation is also available now!
