|The day I was officially cursed was the day I knew I'd arrived as a grown-up Pagan. The curse arose from misplaced anger over an event I had no part in. Nonetheless, I was the target of the curser's wrath and the full-on recipient of said curse, and I was concerned about suffering any ill effects as a result.
My thoughts went immediately to cold iron, a substance known to repel evil, curses, hexes, and malicious magickal critters. The best piece of iron for this is a horseshoe: held or fixed with the points up, U-style, it traps and holds negative or dangerous energies, which is probably why we associate it with good luck.
To ward off dark magicks, walk your bounds-around the house and property-three times while carrying the horseshoe, then mount it over or close to your home's threshold. You'll be well protected.
