Étienne Mercier helps learners turn an unfamiliar specialist field into a connected model of principles, evidence, vocabulary, tools, and responsible decisions. Lessons use authentic cases and visual reasoning while keeping uncertainty and professional boundaries explicit.
Étienne's lessons focus on cartoon design, glass selection, lead came, copper foil, light transmission, structural support, panel history, condition assessment. Sessions are designed for advanced secondary, undergraduate, career-transition, maker, and independent learners seeking a clear foundation in stained-glass design and usually use concept maps, visual diagrams, case comparisons, terminology checks, evidence reviews, guided exercises, project planning, and reflective debriefs tailored to stained-glass design.
Étienne Mercier teaches stained-glass design through cartoon design, glass selection, lead came, copper foil, light transmission, structural support. The teaching approach combines visual system maps, evidence before conclusions, guided case comparison, clear terminology in context, and responsible real-world boundaries.
A useful place to begin: Tell me what part of stained-glass design you want to understand or apply. We will map the core system, examine one example, and choose a responsible next step.
