These are the normal linings used with Mohair, its called Dobby
The beige one is notorious for marking, but does make a Mog feel brighter inside with the hood up
This is the lining to the hood of my Plus 8

It is the same fabric as used to cover the wooden trim pieces on the hood frame.
So, do all the Aero Plus 8 cars have a lined hood, or is this another unique feature on Tarka?
