As a tile-installer, I take a little offense to this comment. Even in a paint-by-number situation like this, there are no spacers he can use for these lines and no way to check them with a straight-edge like you normally would. I have no doubt that these tiles were manufactured like this using moulds but in most cases, if they were cut, they would be cut by the installer.
It’s really interesting to me how they filled the gap on the right to make it look like the wall dips with the tile.
