We present a basic pattern for the main part of the beanie, with several options for the colour work, which is charted, then give two options for shaping the crown of the beanie. Even more variation is possible by creating a fold-up brim, by choosing a different rib pattern, or adapting for double knitting.

A brief introduction to the mathematics of the Sierpinski triangle is included in the pattern.
