what kind of material is this???

when i went to school to get my MECP we did advanced designs
and if you want to do raised 3d logo

for carpet not recommended
tweed - closed cell foam
vinyl - vinyl (cut the design out of vinyl 1-2 layers)

everything is glued first to the panel then you put the cover over it. pretty easy, use a spoon or something. do not use your fingers on some materials like headliner, because it leaves marks.

in my s10xtreme i had a Xtreme logo in my headliner with closed cell foam, then i changed it to the X logo... my friend put
Honda Civic and the H symbol in his... he free handed the designs...
