I am starting to plan out for this christmas and I want to make it look like it has been snowing. I don't want to top dress with white sand because my lawn has been top dressed too many times already and kinda bulges, and I live in Perth so soil quality is already an issue that would only be made worse with white sand. What painting options do I have (I am happy to reapply a couple of times). If I was to just get some regular old ceiling white paint, would it kill my lawn? I figure water based paint is out because it will run when I water my lawn. apologies if not appropriate for this board.
