I am still kind of new to the knitting stuff and I just knit a scarf and did some knit stiches on the ends but obviously it wasnt enough to keep it from rolling up. I thought I could just felt it to flatten it out, but was doing some reading and it says that only 100% wool or alpaca will felt. Is this true? Has anyone else ever felted something not wool. I think mine is 100% acrylic. (I have a feeling someone just groaned and said poor girl - she has a noodle not a scarf).
