Reading the Slope: How to Plan Depth in a Small Moss Terrarium
Depth is the single quality that separates a jar of moss from a landscape. This long-form guide walks through the substrate slope, the three-plane rule, the way foreground grain size controls perceived scale, and the small tricks — hidden risers, receding textures, a cooler colour temperature at the back — that make a twenty-centimetre vessel read like a hillside. It closes with a slope-planning worksheet you can sketch before you buy a single handful of moss.
