DIY Free Knitting Pattern of Marley’s Ghost Chain Link Scarf. Do you remember Jacob Marley, the ghost, covered with chains from Charles Dickens' A Christmas Carol? This pattern is so cool because after you finish the scarf you felt it in your washer which makes it stronger. Tutorial and free pattern from Knitty here. *First seen at Geek Crafts here. *I reblogged a larger chain link scarf by crochet clouds here.
