I created these gloves so that I would have something to knit between classes. I wanted something easy to knit, but more interesting than a simple 2X2 rib. I was taking Anatomy and Physiology at the time, so since I was doing ribbing, I decided to name the gloves for the muscles between the ribs, the intercostals. Thanks to Jennifer Adams, Cindy Chapman, Jennifer Coulter, Dagny Lilley, Meadow Lisonbee, and Anastasia Pelechaty for testing this pattern for me!
