Im installing pergo outlast + in my kitchen, hallway and foyer. There are many areas where the flooring ends width and length wise(lots of coves and such). How do I measure and cut my first row at my starting wall to be able to have a nice professional look, so that board widths are about even at all of the end walls? Same goes for the lengths(need to be at least 6 long against walls). What wall should I start my rows against? See pic below. Thanks so much!
