Well, that's what I was thinking, but it seems complex. Not that complexity is necessarily a bad thing, but.... Anyway. So cast on a number of stitches for the back of the hat, and then start with the increases/decreases on either end, then sew up the middle? That's kind of what I was thinking before I decided to ask a question. (Thinking that knitting it flat would be the way to go.) Anyway, thank you for your reply!
