I previously submitted an outdoor table that was great for all of a few months. Apparently I didn't plan for wood movement and it destroyed itself. I rebuilt the top with cheap cedar fence slats and a better design. It looks better than the first and more importantly it is holding up!
Thanks! There were a few reasons. They are cheap, light and worked with the design. After having the first failed attempt at a top i wanted something I could space yet still make sturdy. These were thin enough that I could make the criss cross pattern that I thought would allow for board movement yet make it solid when having 2 layers. The only downfall is they took a lot of sanding. The ryobi belt sander made it pretty painless though.
