“Mathematics through knitting and crochet,” is the motto of Pat Ashforth and Steve Plummer, who describe themselves as “mathekniticians”. The couple are former maths teachers and live in Lancashire – an English county with a long traditional of producing textiles. There is a wonderful article in the Guardian about their knitted and crocheted blankets that represent a range of mathematical concepts. There are photos of many of the works – some of which are owned by the Science Museum in London – in “Meet the mathekniticians”. And you can buy patterns from Ashforth and Plummer on their Woolly Thoughts website.
