I have an Aero Stockman that I was trying to shift but might have to end up keeping. The lining is a blue, black and white tartan which has just (after 7 years) managed to wear through at two spots in the lower back. The wear looks like it would eventually follow a horizontal line a little way over the hem if left. I am easily capable of patching it with similar-coloured material myself, but should I do it or splash out on a more expensive repair (either with a piece of original tartan or by having a tailor select exactly-matching material)? What do you think it would subtract from the (very goddamn reasonable, gentlemen) sale price? Jim.
