An oldie but definitely a math-lover’s goodie, this Pi Digits Scarf by Christina J is exactly what we need today and the fact that it’s double-knit is just a geeky bonus…

The best part about the scarf? You can make it as long as you want … to infinity and beyond! Read all about it here, get the pattern from Ravelry here.
