What sort of folklore magic do people practice where you are, in your culture or did/do your family practice?

For instance, when I was young my parents always followed the Scottish tradition that on New Year’s Eve someone with dark hair had to bring a piece of coal into the house. The coal was supposed to bring good luck and the dark hair relates to Viking invasions (mostly blonde haired people) that were definitely not good luck.

I was also watching a television programme about early Australian settlers (through to the 1930s) putting shoes and personal objects around the outside of their homes to distract bad spirits.

So what magic folk law are you aware of from your culture, family or local area?
