The best you can do now is... start over with totally new yarn (NOT Coates & Clark!!)
And... can you say, knitting marathon? :knitting:
If it is any help, the first pair of socks I knitted were for my father (I was 13). I finished the first one... and gave it to him for his birthday. By Christmas, I had the second sock finished... and it was his Christmas present.
A couple of years later, he put them in the washer - then dryer. End of socks.
Would this be any kind of option?
