A witch’s poppet is made as representation of a particular person that has generally wronged or crossed paths with a witch at some point in time; there primary use is for the witch to perform revenge spells on although they can be used to aid people too like healing.
To personalize the poppet it should contain the intended person’s hair and nail cuttings or if you can get it there blood, sweat or tears. The other ingredients to be added to your poppet will depend on whether you intend to heal or take revenge.
