Boards across a hall way

how long is the hallway ??
A short one ok if you have to but t long hall way MMMMMM!
Just cut a board anywhere to start for some of the joined boards . A good rule of thumb is joins should be 2 1/2 times the boards width apart from each other . Or you can created a brick pattern down the hall with joins lining up , one left one right and so one !!
