I took the part I the armrest out of the car, surprisingly easy! Just removing 'under tray' and release the top part that only clips in. I then sourced a local upholster, who works on retrimming car and left him to it! He charged me a very reasonable £20 and then just clipped back on...
I was hoping to have some material left over, but had to use the center to get the red lines central, and now he is currently playing with making a gaiter, which isn't any fun on a dsg.... I still got resources of more material as have still got the passenger seat that I may strip but yet undecided
