I'm on some crazy decorating kick this year using lots of real dirt. I've been gluing on props for aging and heaping mounds of it around tombstone bases and other props. My earthy source is a vacant corner in our backyard garden. I've had intentional fun digging a cemetery plot shaped space while filling buckets as needed. I especially enjoyed the Igor feeling last night while gathering dirt during a thunderstorm we had here.
Much more soil is needed... there might be an actual 6 foot deep grave available to rent by
