Ding, Ding, Ding - we have a winner! Thank you!! That was my missing piece. I was going from the outside of the rim joist, 16" until the starting edge of the next joist! Doh!! Something so simple...

Got it all fixed up, going from the outside of the rim joist to 15 1/4" until the edge of the next joist, and then 16" after that.


Now that everything is lining up correctly...What do you think is the best floor pattern? The boards are running perpendicular to the joists, but I know typically, you don't want joints to intersect. This is again, a 10'x16' structure.

Thank you again, Paul!
