Halloween decorating part 3

Decorating with Princess today. We added one more cobweb, and lots of blood. I thought we would not have enough blood to make it look like a bloody murder. As we were trying to make the splattered blood look, I started to chant 'ax murder' each time...Princess had to remind me that it was supposed to be a knife not an ax. It was very hard getting the blood off our hands, since we had to put our hands in the fake blood to make bloody hand prints.
Update: we found some old costumes, so we are going with the murdered trick-or-treaters idea. We also decided that we can reuse the costumes for a zombie idea later on too.
