This nerdalicious multi-gauge cowl is a circle made into a circle with stripes knit according to the digits of Pi. Pi (pronounced “pie” and often written as the Greek letter π) is the circumference of a circle divided by its diameter. This ratio is always 3.14159… (with decimals to infinity) no matter how big or small the circle is!
