I am redoing the patio and a walkway this spring/summer. And I want
to do it myself, (along with the help of some brawny nephews...) I was
reading the other patio thread, and wondered if someone could tell me
the basics of laying the patio.

ie. what layers of what, what layer goes first, I gather I must tamp
between layers right?, how deep should I dig initially? And how do I
figure out how much of each layer of material (ie screenings or sand )
that I should be getting?

My soil is loamy, with some gravel and drains very well.

Thanks!
Janet
