On the slip of paper, write the name of the item you’re trying to find. After that, light the tea light or candle and use it to ignite the paper. Say the spell five times while the paper burns:

I summon the forces you have tied because I need to locate an object.
As this charm is said, look for this item, whether it has been lost or stolen.

Extinguish the candle or tea light after the paper has burned all the way through, and have entire faith that this spell will succeed.
