Pi Squared Shawl Free Knitting Pattern

Updated: Aug 28

A Free Shawl Knitting Pattern For Week 2 of the Pi Day MAL

Colorful knit shawl draped over wooden fence, featuring vibrant rainbow stripes. Lush greenery and rustic wooden planks add natural texture.
The Pi Squared Shawl

The Pi Squared Shawl is a simple Pi Shawl free knitting pattern that’s perfect for beginners. A pi shawl grows in rounds based on the math of π (pi), doubling stitches at set intervals to create a flat circle. Don’t worry—I’ve done all the math for you! This version is knit entirely in soothing stockinette, making it approachable, relaxing, and a wonderful first shawl to add to your hand knit wardrobe.


The Pi Squared Shawl - Knit Sister knitting pattern is all laid out below. If you would like a pdf copy of it, you can pick it up for $3 from the Wool & Wyrd Webshop.

Check out our post from last week Pi Day MAL Week 1 post on the Wool & Wyrd blog for all the deets on yarn, needles, gauge etc.

Here is some other important info before you cast on.

Abbreviations

CO- cast on

k- knit

p- purl

slwyf- slip with yarn in front

yo- yarn over

k2tog- knit two together


CO 3

Rows 1-6: k all stitches

Row 7: k all stitches but do not turn your work at the end of this row. Instead, rotate your work 90 degrees to the right (what was the left edge is now facing up). Pick up and knit three stitches along this edge (one for each garter ridge bump- just do your best, it doesn't have to be perfect). Rotate your tab 90 degrees to the right again (what was your cast on edge is now facing up). Pick up and knit three stitches along this edge. That's it! You did it!


Stockinette Stitch Pattern:

Right side (or even numbered rows): k to 1 before the end, slwyf
