I got a call from this older lady about a back patio. I went and looked at it. Its got about 25 blocks that are a 1 by 1 foot long. There not even. They are a little uneven but she just wanted them to be level the best they could be. She said her family did it 15 years ago and it lasted all up untill this year. I was thinking about forming it with 2 by 4s all around in the shape she wants it. Then just drop in sand and pack it all down and put a roller over it. Then finally lay the pavers in place. I will put up a video to a link later tonight. Let me know what your thinking.
