[pallet alert] Yesterday I finished two cedar wood planter boxes. They are twenty four inches square ( height, width,and deep) with a shelf that is seven inches from the top. I used pocket hole joints but used coated deck screws with exterior wood glue. I made it for my daughter, she showed me something in a garden center and ask if i could do better and cheaper. The answer was yes on both accounts. I think I did pretty good job too.
