[Beware of the Fright]

if you wanted to do a full out decor you could hang up lil bats every where also at diff levels higher up down low you could make them out of black garbage bags or construction paper or just by some even, if you were doing finger food instead of using just a table you could make another coffin shaped thing and put the food on that you should get a bunch of curtains either in dark red or black than musty them up or age them, Red wine vanilla ice creams mixed with red food coloring well that might melt but.. idk i hope these help im not too good at this
