So my mother in law is coming over this weekend and always makes my fianc??s Head Dark. I recent learned that she brings a dark cloud with her of jealousy from an ex how hung himself because she choose her son over him. So I?ve done my salt circle around my home I?m going to put salt around my entry ways. But I got a necklace from a sister and I want to give it to her before she enters my home to keep (Joe the Darkness) out and away from him. What all do I need to do cleanse it before I give it to her ??
