Pi Day is celebrated on March 14th (3/14) around the world. Pi (the Greek letter “π”) is the symbol used in mathematics to represent the ratio of the circumference of a circle to its diameter — which is approximately 3.14159. This cowl is a circle made into a circle with stripes sized according to the digits of Pi. A nerd’s delight!

Gauge – For lace (fingering, sport, DK, worsted) weight yarn, 26 (24, 22, 20, 18) stitches = 4”/10 cm in stockinette stitch. Gauge is not crucial, but will affect finished size.

Needles - For lace (fingering, sport, DK, worsted), use US #3/3.25mm (US #4/3.5mm, US #6/4mm, US #7/4.5mm, US #9/5.5mm) (or size to get gauge) for working in the round (either 16”/40cm circular, double points, two circulars, or a long circular for magic loop).

Notions - Tapestry needle, stitch marker, waste yarn.
