I love that table. DH is always picking up crates for making tables for the green house. We've even used them to make fences and chicken coops. The one thing I would change besides the height is I would make it to hold pots instead of planting them directly. It's eisier to find places to put pots when I bring them in come winter than a whole table.
I've got the scrape pieces (old barn wood), I just need to stop by the newspaper office or the small engine repair/sales place and pick up some shipping crates. They usually have them or pallets, which is generally made the same way. Pallets are easier to haul home in the Blazer.
