I am considering putting in a limestone walkway around a cabana seating area. I need some advice on what to use as a border and what to use for the base material to hold the limestone rocks in place. Do I need to prep the area by leveling it first and laying down landscape fabric below the base material? Is bend-a-board good for the border? What about using decomposed granite for the base material to set the rocks in? How many times would I need to spray the walkway down with water to get the stones to set properly in the base once I lay the rocks? Any help would be greatly appreciated.

Thanks,
John
