Well tonight the rain held off and I was able to fill in the cracks with a hardening sand. So after a day of hardening I can clean it off and it will be ready for the weekend. I'm not good at things like this, so I do not often take on such projects, but I wanted to give it a try. It's not as flat as I would like, but I had to convince myself that enough is enough. I took up the pavers and put them back down at least three times trying to get it as flat as possible. I finally said that's it. Now tomorrow I can hopefully finish the last of the border bricks around the patio, then we can begin planting.
