Design by Oui Crochet.
This adorable team spirit earflap hat is designed to fit a small child. However, the pattern links out to a size chart to help you crochet this to any size that you need.
And if you like the little football that pictured, the pattern offers a link to that as well.
To crochet this you will need a worsted weight yarn in your teams colors, an I and a J crochet hook, and a pom pom maker.
