Ooooh interesting rabbit hole. Very good idea you have here.
did you press the punches into the foamex?
When using them for embossing leather, usually a good sharp hit with nylon hammer is required to get a good permanent impression into it.
I don't do much with terrain and definitely not Foamex, so not occurred to me to mess with them that way.
That works fine for leathers but might not be so valid trying to get a good indentation into something like foamex?
That shot plate looks like it would make nice "shields" especially now I looked and they are 8 and 10mm with a deapth of abou 1.4mm
Now I need to get out of this rabbit hole
