A question for anyone who actually works with Santa Muerte

I’ve been working with Santa Muerte for a little while, and it’s been really fruitful. Obviously my situation is a bit complex, but it is improving and I’m feeling better than I was.

However, I need to do another working with her soon - hopefully next week.

My question is about the tributa. Which, for me, typically consists of a small unglazed clay pot, water, 7 silver coins and 7 white flowers, taken to the cemetery and offered as a gift to Santa Muerte.

I know Conjureman Ali recommends the one I’ve described, but are there any other alternatives?

Are there any rules about what you should offer as a tributa?
