There is this pattern at GarnStudio.
Also there is a thread at Craftster--do a search for Panta. The thread at Craftser uses a formula of measure your head, divide by 10 and that is the length of each section, except section 5 which is twice that number. I think this would make the headband a bit too big. So, maybe if you subtract and inch or two, it would be the right size. KnitQueen helped me last week with what type of increase to use, since the GarnStudio does not specify. That thread is in the how-to forum.
Would anyone be interested if I posted this as a Quickie Little Knit-Along? I should have my yarn by Friday. This would also be a great stashbuster project. If anyone is interested I can also post my modifications.
