If you know it’s the right headstone, crayon rubbings will sometimes work. My 
dad used to do that with worn headstones and it makes it much easier to 
decipher. Just place a piece of paper over the stone and rub it with the side 
of a crayon. 
It’s not quite as useful if you have a large number of stones that are worn and 
you need to identify which one is of interest.
