I agree about the importance of a sub-base. When I did this, though,
I used all sand instead of gravel and sand. I was thinking that if I
put down gravel, then sand, the sand would gradually sift down into
the gaps between the gravel stones, leading to unevenness. Wouldn't
that happen? Anyway with all sand on top of my clay subsoil, it worked
out fine for me (still even several years later). -- H
