Casting Instructions for 'To Find a Lost Object'
Write the name of the object you are looking for on the slip of paper. Then, light the candle or tea light and ignite the paper with the candle or tea light. As the paper burns, say the spell five times:
I call upon the forces that you have bound, For an object of mine needs to be found. Whether it be lost or stolen, Seek out this object as this charm is spoken.
When the paper has burned completely, blow out the candle or tea light and have compete faith that this spell will work.
Hope it comes your way. And hope you know I'm not really trying to be mean.
