This is a "recipe" I have developed over the years - I have used it to create hats for my children, and more recently, these two hats for myself:
I initially wrote up the pattern in mathematical shorthand, which to my (admittedly unconventional) mind is infinitely more clear and elegant than words. I have since fleshed it out with verbal descriptions and conventional knitting notation, but elected to leave the math notation intact for those of you who share my inclination to cut to the chase.

I would be extremely grateful to receive any and all feedback as to clarity and ease of use.
