I have a rule of thumb about witchy remains–
If it is baneful workings, something you want to get away from you, or something you don’t want back in your face, take the remains and go for a drive as far away as you can, and bury them…
If it is a drawing ritual, a healing one etc…bury them in your flowerpot to keep close to you.
I never dispose of any in any garbage… don’t know who may touch or find them, and sometimes garbage comes back closer to be disposed of.
Just my take on things.
All of my offerings to my Gods and Goddesses, are taken out to my trees and put around the base of them, and I ask them to please accept this…
That is just me. Any other ideas???
