This sounds like a wonderful idea, I love the idea of putting crystals and flowers or incense inside…
I don’t have much experience with spells, I tend to use my intuition and go by how things make me feel.
I’ve always had angels around me and this is why i would add crystals etc.
I’m very new to the majick side of things but I’m keen to learn more over time…
You’ll have to let us know how things work out and the things you added to the jar…
Blessed be
