Oh, hang on.
If you are turning the brim 'inside out' you may find that the ribs don't line up, if you see what I mean, as the wrong side will become the right side.
I agree with Retread that badly written patterns are annoying
. I think you are going to have to work an inch or two and see what it looks like. It might not matter if the brim rib doesn't line up, or you might have to bite the bullet and pull it out.
If you can take a photo of the pattern, preferably with a picture of the hat, we can take a closer look for you. Or if it's on Ravelry, link us up.
