My mate is after some chess board like 4" squares type flooring but light blue and white not black and white. I have seen this in vans at shows but can't find any on the net. Madmatz only supplies it in dark blue
Madmatz have tiles called wedgewood that you use with white or cream but only the single tiles not the vinyl sheets/Lino.We used the separate tiles in our van and it was reasonably simple to do.
