I found a vintage crochet pattern that spoke to me about my favorite holiday. I lightly modified an old pattern labelled 'A Pretty Spider Insertion in Torchon Effect.' I didn't know what 'torchon' meant, but I did like the spider-like image in the middle and decided it would make a great black scarf for Halloween. And I couldn't resist looking up torchon online - come on, you're curious, too, right?
Pattern available at my Etsy store.
