Here is the fence I decided would be good for the planters. It also has fresher wood than a lot of the other parts of the deck since this was rebuilt before we moved in because there was so much dry rot in the planks.
I marked with an X all of the places I would be drilling. I own ONE pencil and some how that pencil is always available for crafting and I always need one for something. One freaking pencil. I have an entire JoAnn Fabrics and Michael's warehouse in my crafting room and only one pencil. It makes no sense.
Here I am drilling the hole in the X.
