For the lettering I printed up silly names to place onto the Styrofoam tombstone boards:

Using a ball point pen I followed around the lettering which left an indention on the surface:

Using a Sharpie helped make the lettering easier to see:

I’m not sure if it was the Sharpie ink or just by me pressing while writing but there was a nice indention left after filling it in.  I wanted it deeper so using a soldering iron I melted out the black areas

If you decide to use a soldering iron you may want to practice first on some scrap.  It melts quickly and you have to keep moving.  Next I’ll finish up the painting and some other details like weathering and moss.
