The process starts with a carefully prepared base: compacted gravel and sand that allows slight movement without collapse. Each stone is then placed by hand and tapped into position with a mallet, not randomly, but at precise angles. Irregular shapes are intentional — when stones are set tightly side-by-side, their un
