Mine was in a very poor state, so when doing the black leather highlights in my car, I started on a recover myself.
Very tricky with much thicker leather, but I'm reasonably happy with teh results so far.

Before someone says, the gear pattern boss is not yet stuck in, so it's popping out on one side.

Never really quite worked out how to finish the underside though, so it's been sitting by my computer for a couple of years now.
As picture shows, the steel insert is just a press fit in originally. Touch of epoxy when I finally decide what i'm doing will keep it in place ( assuming I use it).
