My sister knit me this pretty scarf from Fun Fur, which is kind of a miracle because she is usually only a crochet person. I am (naughty) a smoker! I am wondering how I wash this scarf so that when she comes to visit me, or when I visit her, the scarf she made so lovingly for me does not smell of smoke (which she hates)! I believe this yarn is 100% acrylic. Could anyone help me please?
