Today is March 14 or 3.14, the short version of Pi. I’m not sure when folks starting celebrating Pi day. I am sure it was some geeky types that got it going.

Pi is actually much longer than 3.14. Figuring the decimal digits of Pi is a math problem without a final solution. Mathematically Pi is referred to by the number of decimal digits, ie… 3.14159 is referred to as “Pi to the 5th degree.

A couple of years ago I posted my “Pi recipe”. Where I showed you step-by-step how to make crown down hats that fit using Pi.

So if you want, today you can crochet a hat as part of celebrating Pi Day. Have fun.
