That was my first thought too. Different stitches such as knits and purls could serve very well as dots and dashes. Maybe that could've been too easily spotted.

She transmitted her messages via radio, which allowed her to skip the messy business of smuggling knitted intelligence out of occupied France.

That being said, I'm 100% stealing the knitting-as-writing concept for a TTRPG campaign. It's just too cool of an idea to go to waste.

Thank you! I remember learning about this in an art history class decades ago, but I'd completely forgotten and I never would've remembered the name.
