@ColinTheMathmo @MathsJam @BigMathsJam I'm both a computer person and a maths person, and I was doing fiber crafts before I was even aware that I was either of those.
I have a booklet somewhere that is aimed at later years of high school, that is about math and knitting. (In Dutch, otherwise I'd have been looking up a link right now.)
@wynke The connection between maths and fiber crafts is anecdotally well-established, similarly to maths and music, maths and juggling, etc.
I'd be interested in the booklet you mention. No rush, just make a note of my interest, and if you happen to find it, let me know.
@ColinTheMathmo @MathsJam @BigMathsJam I arrived home since and have found it. It's part of the 'Zebra-reeks', which is a Dutch series of mathematical materials that aren't part of the standard curriculum, aimed at the final years of the highest level of high school (pre-university) in the Netherlands.
