Sometimes it's the simple things that make me smile when it comes to Halloween props. This "Meat Hook Chain Garland" is so simple (and inexpensive coming it at only $13.59), but hang several of these around the house, in your dungeon, on the garage door or even out the back of the car window, and you could probably scare a few people. Or many.
These are made out of plastic, are 12.0 " H x 12.0 " W with a 3.0" depth. They were originally found at Target here (though they are currently sold out). (skull and death figurine not included).
