How to use this prompt

The toothed-trowel ridges in the unset mortar are the realism anchor — they show the mortar was combed and is fresh, and they give the surface a texture that plain smooth mortar lacks. Set 'neat rows already set' beside the one being placed so the viewer reads process, not a finished surface. Keep the palette restrained — cream and terracotta — because a rainbow of tiles turns it busy and the single placed tessera stops being the focus. Even light matters; a hard shadow across the mortar bed hides the ridge detail that sells it.

Variations to try

Overhead — a larger section of the pattern with the working edge visible
Byzantine gold — gold-leaf glass tesserae for a richer, historic palette
