Oh geez and I tried so hard to keep the water the same temperature!! I haven't tried to knit any yet so I couldn't answer that but they still are rough after I make them into balls. And it's not like they are super rough just enough to irritate me!
I thought I read online somewhere although i can't find it now of course where there was something you could wash your wool yarns in after they dying process to further set the colors and to make them super soft again? Maybe it was only a dream!
