I love woolly nylon for socks. The first socks I made were self striping out of Jawol yarn and it came with their nylon. It was ok but I found it rather thick. Once I started on other socks I read a few posts that suggested woolly nylon and decided to give it a try. I really love it. It comes in a huge variety of colors and I've always been able to match it and you can't see it once the socks are knit up. It wears and washes well also. My one sister insists on machine drying the socks I made her and it hasn't affected the nylon at all. I've always gotten mine at Joann etc so I can properly match it. I once was positive I needed more of a grey and turned out when I put the yarn against the woolly nyon I needed more of a brown.
