I also spent some time today working ont he small "snacks tray" that fits in front of my centre console. I made up a false bottom (to prevent small items getting stuck down in the otherwise tight bottom corner), and lined with felt. I then cut some leather and glued in place with clear contact adhesive. This is the same leather as the seats, and centre console, so matches in nicely with the rest of the interior.
