The Hidden Pi Cardigan is not only the right cardigan for math nerds! The lace-pattern, which is knitted across the body of the cardigan, contains the first digits of the number Pi and makes the cardigan special.
The cardigan is worked seamless and from the top with yarn doubled. I used Sunday by Sandnes. The Hidden Pi pattern is included as a chart.
