Spellboxes are fantastic! They can take on any size, shape, color, etc. They are open to your imagination.
I see a Spellbox as a vessel to send my wishes to the Universe.
I like to use jars.
You can fill a Spellbox with all kinds of magic. Notes with wishes (written as if they already are: “Money comes to me easily”, “My body is strong”), herbs, rocks, glitter, treasures. For money spells, I add coins & bills, or shiny things. I always add herbs that support what I am asking for. I like to add rocks or other things I find on my river walks. As I am adding the items, I speak to them and let them know what their role is.
If I want to ban something from our lives (this can include health issues, bad bills, etc), I make a separate Spellbox and line it with aluminum foil. I write the things I want to ban on little slips of paper, and again, read them out loud as I add them to the jar.
There are no rules. Spellboxes are intuitive. You add what feels right.
Once you are done, you want to give it one more blessing or instruction, and a thank you, before you seal the lid. I just put glue around the rim of the jar before I glue on the lid.
I put mine out during Full Moon to enhance the magic, and bury them the next day. Sometimes on my property (if they are prosperity boxes), sometimes in the woods (if I am banning), or by the river (because the river is magic :)…).
This is also a wonderful thing to do with children!
Happy Full Moon, Beautifuls!
