You guys have been great with answers and have very knowledgible People on this site... So the next DIY project that I have is a Patio.

I am planning to use Envirotile's for this project.
My plan is to build a 180sqft frame out of treated 2x4's and placing them halfway to 3/4 of the way in ground to use as edging.

Next, I plan to layer the inside of the frame with weed barrier fabric to kill all weeds and grass.

Then, fill in the frame with leveling sand to set and hold the tiles in place.

The GOAL is no digging.
The area that I will be working with is not level. I would post pictures but this is my second time on this site and don't know how to yet.

Will this Work?

Any good experience with installing stone pavers or Envirotiles would be greatly appreciated.
