yup, I'm terribly allergic to wool, otherwise there wouldn't be a problem. I can't even wear wool on my feet or knit with it, so I need a good alternative. In my old tread I've received some options, but they are not available in the Netherlands. That's the main problem. I went to my LYS, and they told me that sometimes the do have sock yarns without wool, but not very often and not at the moment, so that's why I knit with acrylic. I've just finished the first sock of my second pair with a short row heel and I really like it. I just don't want to use 100% acrylic, and cotton with elastic or with lycra isn't available in the Netherlands. That's the reason of my question, but since someone has good experience with that, I might give it a try and see for myself wether it works out or not.
