And for those of us who are knitters, it means the incredible Pi Shawl, who are first attribute to the amazing Elizabeth Zimmermann, the grandmother of knitting!
Want to knit a Pi Shawl? Here are some amazing shawl links and my faves if you are so inspired (in no particular order).

Spanish Peacock Shawl
EZ 100th Anniversary Pi Shawl - Hearts

Me, I've at least four on the needles and just wish I had more time to knit all the Pi Shawls. VBG! Happy Pi Day!!
