I have BR-111 1/2" x 5" Engineered wood in random lengths.

I have something like :

12" 's
24" 's
36" 's
48" 's
55" 's

I know people say use a trim piece to start a new row, stagger joints 6-10", etc

My question is, with all of these set lengths I have, is there some kind of "science" to placing these down that makes it the easiest method?

Any opinions?

IMO completely random is the desired look. No science to it, I dont like to detect any pattern. Just be creative
