The most famous Pi Shawl is of course Elizabeth Zimmermann’s. Originally shared in her print newsletter, it’s been republished in Knitter’s Almanac, where it’s the project for July because it’s “good travel-knitting.” She likes this particular project for its simplicity, with only six increase rounds in the whole project.
Towards the end, by the time your state of mind has become more and more frayed, and your need of mindless comfort greater and greater, your knitting will be nothing but almost endless rounds of hundreds of stitches, with no thinking required, at all. You will end up with an heirloom.
Sounds pretty good, right?
There are lots of great pi shawls out there in the world now; here are a few.
The Simply Pi Shawl form Kay Meadors is really simple, almost all straight knitting. An optional beaded edging gives it a little sparkle and weight.
If you’re willing to pay a bit for a pattern, check out Mindy Vasil’s Camellia, Susan Pandorf’s Evenstar (you’re going to want to look at the amazing variations on this one, including a knit dress), the Butterfly Pi shawl from Linda Farrelly, Margrit’s Pi Shawl by Tanja Luescher and the Diamond Rings Pi Shawl by Donna Druchunas, who inspired me to collect this roundup in the first place.
And if you want to go your own way with a circular shawl worked from the center out, Holly Peacock has a great calculator in a Google document that you can use. Just plug in how many stitches you want to cast on and it will tell you where to increase, how many stitches you should have once you’ve increased, and how many usable rounds you have between increase rounds for plotting out your pattern. Awesome.
