O.K. I finally wore my new socks out and about this weekend and they are warm - dead of winter warm - the kind of warm I only need a few weeks out of the year. Yes they're wool, fine and dandy but I want to make socks that are comfortable year round. I'm really frustrated trying to find cotton sock yarn even on the internet. I don't want my socks to be all colors of the rainbow - a nice gray or beige marl would be great but I can't find it anywhere at least not using "sock yarn" for the search. So what makes a sock yarn a sock yarn and can I use any cotton in the right guage for socks?
