I really love this cowl. The small version is now my go-to scarf for my small son. I've made couple, each in different colours, to match his winter hats. He can pull them on easily, and I don't have to worry about him losing them in the playground.
The pattern itself is excellent, like all of June's patterns. She has great directions on fsc (which I used to struggle with), as well as diagrams dealing with how the mobius works, and a great chart to help you figure out how to make the right sized cowl. It is wonderful that the pattern is available free, but it is more than worth a donation to get the nicely formatted pdf.
