Out of curiosity I am asking myself why interior design boards are made like in the photo bellow:
black foam core, and stuff glued onto it incl. material samples.
Personally I would color correct scan in the material samples, design a presentation layout
and create a material box to hand it out to clients so they can touch it without damaging the board.
This seems to be very typical for the US - how are other countries?
Now considering here are also Blender users I am further more interesting in how you would do it?
In Industrial Design I teach my students simply the way I would do it as a graphic designer.
INTD seems however to be different personally I feel like stuck in the 80s.
