I found a pattern for a hat that I loved. The hat is a knit ear flap hat. I have been knitting for a few years and decided to make something different. I am making this hat for 4-H and I just got done knitting the hat and found that I had to crochet the bottom of the hat around as the edge of the hat. I don't really know how to do this at all. I have tried to learn but I really can't figure this out. Please help me if you can!
This is what the pattern says to do:
With right side facing and crochet hook, attach yarn at center back; ch 1, sc around lower edge of hat, including earflaps, taking care to keep work flat; join with a slip st in first sc. Fasten off.
