I tiled a floor with tiles made of cheese today, the floor needs replacing every month as it starts to get very smelly. They are regular customers of mine and love having me in the house every month to replace their floor, sometimes it's Stilton, sometimes it's cathedral city. I find the best adhesive to use is dairylea and Philadelphia is perfect for grouting. The finished floor looks lovely and is very soft underfoot. Next month they have asked if I can fit UFH before tiling with babybel tiles, I've advised against it as I think the cheese may melt.
