I recently made a second chunky circle scarf from people web's tutorial for my sister and her new coat. For the first scarf, (here), I used a bulky weight yarn, and for this one I used super bulky.
With my big blue plastic hook which I think is a size Q, and Lion Brand's Wool-Ease Thick & Quick, I chained 91 and only needed to crochet rounds 1-4 twice in the pattern. It worked up really fast, and it felt like I was either using a giant's crochet hook or that my hands had shrunk.
And here's my sister with her scarf and new coat! The yarn matches really well with the plaid flannel lining! Success.
