Hi guys, I’m going to box the back lawn in with 8x1 timber so that I create a border to then infill with pea gravel, it needs to be 8x1 to get to the level of the path and a patio the other side, the question is, when the framework is finished, what can I fill in the void with, before the last 2 inches or so of pea gravel? I’m guessing at large stone before the pea gravel goes on top? Am I thinking I’m the right direction so far ? Any help appreciated. Attached should be an image of what I’m talking about
