“Pure mathematics is, in its way, the poetry of logical ideas.”
- Albert Einstein

Elizabeth Zimmerman’s pi architecture for shawls has such a mathematical simplicity to it—double the number of stitches at a halving rate—that pleases the scientist in me. This formula results in a flat circle. To celebrate the mathematical beauty of pi, this shawl uses the simplest of lace patterns. Increase rows disappear into the overall pattern, with one extra increase round at the end to produce a hint of a ruffle. This light and airy small shawl is easy enough to knit while pondering other mathematical mysteries (or watching TV).

Note 7/19: An eagle-eyed knitter caught an error that my tech editor and I both missed - the yarn specified in the pattern should be “sport weight”, not worsted. If you would like to knit this in worsted weight, never fear! It works great at all weights of yarn. Worsted will give you a larger shawl for the same number of rows. You’ll want to use larger needles to get a nice drape - I suggest US10/6mm to US11/8mm as a good starting place - and may need a different yardage. I’d love to see your photos, whatever weight you use!
