It's hard to say without seeing the pattern. Is in on line?
My guess is that each section of the hat, whether its a cable or the pattern between the cable may have been given a number? How many separate sections are in the hat? If there are 8, then that's it. If not, more information would help.
I just googled the hat and saw the pattern picture for it. It does look like it has 8 sections. Yes? Am I off in left field?
