Scrib cabinet kickboards how please?

Hi I am just about to start renovating the girlfriends kitchen. I have done this sought of work before, so mostly I know what I'm in for *sigh* :roll: But the one thing I have never been able to work out is how do you "scribe" a cabinet "kick board" so as the bottom edge of said kick board, follows the ups and downs of a less then perfectly level kitchen floor? Would be very interested to hear from anyone who actually knows how to achieve this mysterious concept?
