Pi Scarf

Difficulty: Easy
Time: 22 hours
Price: $20

This pattern is available as a PDF! And can be found on Ravelry!

I like pi a lot. In fact, I like pi far too much. It's been that way since 5th grade, and that's quite a while. My desire to make a scarf like this is why I always wanted to learn how to knit. So, I had youtube teach me to double knit and then I was all ready. Once you finally cast on the doubleknitting, the scarf is super easy and all it takes is time. Flying across the country twice in two weeks is good for that. Plus, knitting on airplanes makes you the most interesting person ever.

Anyway, the pattern:
Needle Size: 13 US (9mm)
Yarn: Bulky, contrasting colors
Brand: Loops and Threads Charisma
Skeins: Two of each color.
You could use just about any yarn weight and needle size depending on how thick and long you wanted the scarf. Mine turned out to be 42 digits long, about 7½ feet long and 6 inches wide.

The entire scarf is double knit. The pattern is super easy. Each number has two rows between it. The chart shows the start of the scarf, 3.1415, and then the remaining digits you need.

Here’s some mathematical constants to a bunch of places. Have fun!

Just keep going with numbers until you have a scarf that's long enough, or you get sick of your project or you run out of yarn! Here's my 42 digits, it was a good number to run out of yarn on:
