1. one sheet of 510x760x5mm foam board. I used white, as it was easy to write on and2. one packet of map pins that I found in a drawer. I ended up colour-coding the mock-up with the different-coloured pins – I’m not sure if that will be useful, or if it says more about me than I would like3. a cutting board – I used a large green cutting mat, as it has useful guides that help to keep a cut line straight4. a sharp cutting knife5. a metre-long steel ruler6. a pair of scissors7. an artist’s paintbrush – or anything thin with a rounded end8. both single-sided and double-sided tape9. a soft pencil to go over the outlines that I had pressed through into the foam board10. some correction fluid in case I make a mistake that can’t be rubbed out or cut out – it works well over toner11. the trigger mechanism that I had bought, as I’m designing the crossbow around it.
