So my dad and I are making a stone terrace, to do that we apparently need to build two small retaining walls, level an area, put gravel down, put down sure pack (a special type of stone/sand), and of course lay our stone. We've already dug our trenches and started putting in the retaining walls today. Any advice you guys have on this sort of thing?

Neither of us has ever done anything like this, but we have looked at some books and spoken to some "experts" so I think we have a fairly good idea of what we're doing, and we definitely have enough supplies. I'd just love to hear if you guys have any tricks of the trade to share with us.

Oh yeah and I'm fairly sure we're working with field stone of some sort for the walls and I know we're working with blue stone for the terrace.
