Below is a list of free sock patterns I have come across on the Internet. Not that I will ever accomplish this, but these are all socks I would knit if I had the time. Who knows, maybe by the time I am 80 I will have made them all! The astericks will designate which ones I have actually finished. The first link shown is to the pattern, the second to the designers blog or Web site (if they have one).
