In this series we share a selection of craft projects with a maths twist, or perhaps some maths projects with a crafting twist – you decide. They involve a range of skills from knitting and crocheting to cutting, folding and colouring in. Many have a link to some interesting maths which you may like to explore. From creating a Klein Bottle to knitting a Pi Scarf – there’s something for experienced and new crafters alike, for those with a passion for maths and others who are simply curious.
If you feel inspired to give any of these activities a go, we’d love to hear from you and see what you produce. You can email photos of your finished projects to outreach@exeterms.ac.uk
Happy crafting!
