Jen Hunter : Yes, maybe as a seat cover on a nice chair or under a glass table top? Leather on the walls could be cool, too... The floor just doesn't make sense to me, I can also imagine it getting scuffed up and ratty looking, shredding in high traffic areas.

It does look amazing, though!

Yeah, this looks practical!

-What would you clean it with? Leather cleaner would be expensive for a whole floor.
-Can't spill anything on it or get it wet, it would absorb into the leather.
-Can't easily get the dust and dirt out of the notch holes and grooves.
-Starts rotting after about 5 years.
-Images of hundreds of men not washing their hands after using the bathroom = stinky used leather belts that are in surplus because the whole idea of a used belt is gross.

$70 a sq ft? Sign me up! lol. The "rug" seems a slightly better idea than the flooring tiles.
