Part of the Greek Patterns Collection, Delphi is an interlocking key stamp that runs as a repeating border across clay. Each unit reads as an upright pillar linked by short bars to the next, the I-shaped forms chaining into a steady columnar rhythm, the kind of measured fret that ran beneath temple pediments and along carved stone friezes. Press it along the rim of a plate, wrap it around a vase, or run it across a flat slab for a structured decorative band.
