Being a chunky gal, I never, ever knit with chunky yarn because chunk + chunk = double chunk and who needs that.
Sometimes, though, I do love using chunky needles.
Meet the back of Lucy Lu. The yarn is Malabrigo worsted. The needles are #13s. I cast on two days ago.
It's pretty. It's simple. It has a drop stitch border around the bottom of the back, fronts, and sleeves.
