Have a 12x20 shed on 4x4 skids coming, need to prepare a crushed stone pad to set it on. I'm trying to figure out what material to use as a border/wall to keep the crushed stone retained. I would like to use the 6x6 landscape timber as shown below (I think they look a little nicer), but I can't find them anywhere. Is a pressure-treated ground-contact rated 6x6 enough to suffice?

Any other ideas/suggestions?

PT would work well.

just drill them and knock some rebar to hold them in place..
