   Oboenwerkstatt – Yvonne Schachner

   Designkonzept: Werkbank statt Hochglanz. Palette aus Ebenholz (Korpus),
   Knochen/Pergament (Papier) und Zinn (Beschläge) mit dem realen Logo-Rot
   als seltener, präziser Akzent – wie der rote Faden an einer neuen Rohrblatt-
   Bindung. Eyebrows als geprägte Werkstattplaketten, Lineal-Teilstriche als
   Sektionstrenner: die Website denkt in Maßeinheiten, nicht in Deko.
