 dig a hole about 2.5" deep and the shape you want.  Using a sack of
 concrete mix (and preferably adding one of the fiber amendments that
 replace wire reinforcing), pour and level the stone in place.  You can
 also dust the surface with powdered concrete dyes and/or mix in colorants
 to make the concrete belongs in the area.  Or you can scatter some
 of your soil on top and sort of trowel it in a bit... it usually results
 in a bit of coloration and a slightly irregular surface more like
 real stone. >>

While this sounds like a simple effective idea, I think in zones 5 and further
north where deep in ground frost is present in winter months, more care is
needed to use concrete.

Nearly everything without drainage beneath will heave.  Our area of the world
is littered with cracked walks, walls and foundations.  Those forms sold in
catalogs for garden paths do not produce durable walkways in zone 4.

Hypertufa troughs are not left outdoors in the winter months in zone 4.

We can have solid frost to four feet in the cold months.
