TIME FOR SOME ABRAHAMIC MYSTICISM!
LET ME HELP YOU ANONS!
It’s a Jewish and Christian mysticism thing, which basically amounts to either a “Return to Sender” charm or acts as protection from curses, ill will and similar items aimed at you by the “evil eye”. The “evil eye” amounts to basically any jealous, scorned or nemesis-like person casting “bad” at you with their eyes/looks. Get those charms; they’re good protection or just good aesthetic pieces. My grandmother had a lot of old-world knowledge and rituals; she always had us put those charms on every door/entry of our homes facing outward.
I’d recommend the door hangs on all doors, and put one or two larger pieces up or painted on the front and back of the house outside, plus get a keychain and/or bracelet and one for your vehicle. Also crucifixes over every door of your house, inside and outside of rooms and the home itself, which may seem like a hassle but it’s good for deflecting evil and “white lighting” your house from spiritual harm.
You can also place a rosary or scapular on the interior doorknobs or near entryways leading outside.
Get a chicken’s foot (preserved or shellaced) and place it where people can see it upon entry of your house, both front and back (and/or side entries) work wonders.
Only other thing I can think of is protection jars/spell jars of protection but that’s better left up for anons to figure out what suits them.
There’s also the fact that some people swear by organite being taped or placed on your main water pipe that feeds your home, and if you do use organite (as it is new age-ish) look toward holy geometry and the tree of life for the shapes embedded or engraved on your pieces for added protection. It’s just a resin and a specific mix of ingredients to “cleanse” your living area’s energy.
