Grandma would usually employ the devil horns, but sometimes the fig gesture was needed. She also had in her arsenal a double crucifix made with the middle and second fingers on both hands interlaced. The evil eye is powerful, y'all.

I've been reminded of her lately while watching Constantine.

Hubby's relatives and friends in Hawaii had a ton I had never heard of.

Never put your feet on a pillow or you will have upside down thinking and confusion (dementia)
Never face the foot of your bed towards the door or evil spirts will drag you out the door. Also never set your desk so your back is to the door or they will attack you.

Never take a rock from a volcano -- Pele again- will bring you bad luck

Celebrating a childs birth before one year will bring it bad luck and sickness.

Put a screen or a wall up so you can't see from the front door through to the back yard or the devil will travel through your house instead of going around.

If you take a picture with three people in it the person in the middle will die first.

I am sure there were a lot more but I don't remember them all.

The one that got me was giving a gift to near strangers for any reason at all. They spend a fortune giving junk gifts to each other.

A bird flying in the house or trying to get in the window was a bad omen.
