The method is much different in the frozen north than the sunny south. I do not like crushed stone with a gravel overcoat. the sand will eventually settle into the stone and leave voids under the pavers.. I am a firm believer in stone dust. 3/8 stone dust, wetted and compacted is like a concrete base.
