 We sewed the bottom of the cable tie to the servo motor and used the hole at the top of the cable tie to thread the yarn through. We needed to stabilise the '​needle',​ so we added a piece of wood along the centre of the machine and a pathway for it to go through - for this we used a piece of a straw. We sewed the bottom of the cable tie to the servo motor and used the hole at the top of the cable tie to thread the yarn through.

 As well as taking part in planning discussions,​ my specific contribution to the project was cutting the wooden pieces to go across the loom, drilling the holes for the needles and helping to sew some needles to the motors. As well as taking part in planning discussions,​ my specific contribution to the project was cutting the wooden pieces to go across the loom, drilling the holes for the needles and helping to sew some needles to the motors.

-In order to digitalise our prototype, Liane designed the wooden structure in Illustrator so that it can be laser cut to size. She also designed needles that could perhaps be laser cut too, although we would need to research this a bit more regarding which material would be best. We would also need to test if the length and joints work well.
