I laid out a pattern on a sheet of 1/2″ plywood so that I could cut out eight supports.  It ended up a little short and flimsy but it is just enough to keep the boards organized and up off the ground.

I picked up some 6′ threaded rod and cut sections of PVC as separators.  Threaded everything together and covered the PVC with some pipe insulation.  Awesome weekend project and room for one more board that’s under construction! Woo Hoo!
