Get a Little Irrational: It’s Pi Day!

Okay, so maybe you haven’t heard of National Ear Muff Day, which just passed yesterday, but if you’ve been anywhere near a secondary school math classroom in the last decade–or have math nerd friends like I do–you’ve probably heard a thing or two about Pi Day. The Reader’s Digest Version? It’s March 14–3/14–and Pi, the irrational number that is related to the circumference and diameter of a circle, is approximately equal to 3.14, though the decimal places are though to go on forever. You can learn a little more about Pi here, or you can just dive in to some of the fun mathematical-themed knitting and crochet patterns I found on Ravelry to celebrate Pi.

One of the best things about Pi Day in high school was that there was almost always pie. Growing up outside of Philly, it was a special treat to have TastyKake pies delivered warm from the bakery, straight to third period algebra. Since Pi Day is only half as fun without its more delicious homophone, I’d love to share some calorie-free yarn pies with you as well.

Now that you have a truly well-rounded palette of options to celebrate Pi Day with yarn crafts, how do you plan to observe the day? Math? Pies? A good book? (Why not Life of Pi?) Leave your Pi Day memories and celebrations in the comments.
