I used to set a table in my spooky kitchen with dirty plates and silverware featuring some burnt pieces of wood with motor oil on the plates and some dried lawn trimmings sprinkled over everything.
Nobody ever mentioned anything about this, mainly because it fit right in with all the other stuff in that room! "Continuity, continuity!"
Not having any money at all when I started this place, I went over the bluff behind the house and dug up some antique bottles from the 1910 landfill and put them in my Spooky kitchen with new labels of products I invented, and these were my inexpensive props for the kitchen routine for many years.
I got alotta "miles" out of basically "nothing".(by common standards)
