I know absolutely nothing about knitting let alone knitting chart keys but this great tutorial developed by Kalani Craig
is a wonderful introduction to computational textiles for crafters.
Craig combines knitting with the computational powers of the Lilypad Arduino to create a handbag decorated with 10 LEDs that act as a row counter and a charted pattern.
Watch the video below to learn more about the project.
