The old concrete slab patio in my back yard was worn and cracked. It was oddly shaped, with a weird cutout for plants on one side, and ended a few feet short of the corner of the house. It was also slanted - so much, I had to park the lawnmower diagonally to keep it from rolling down the patio. :P There was a little makeshift deck for the back door (which had originally been a window).
The new patio is a rectangle with rounded corners, and it extends all the way to the corner of the house. The deck is gone, replaced by a single step.
The stamps gave the concrete the texture and appearance of slate pavers. A definite upgrade from plain old concrete! :)
