The Upside Down Spell

First, take a clean jar and clay. Use the clay to mold it into a poppet, which will represent the target. Leave a bit of space inside the poppet to add the taglock and sigil. Once that is completed, take some glue and add it to the feet of the poppet, then proceed to glue it inside the jar. It needs to be stable, so the poppet shouldn't move. After that, pour the water in the jar and add your assorted choice of nasty things, I like to use trash and dirty shards of glass. Try to tie the items to your intent with the target.

Close the jar, and shake it, making sure the dirty items are touching the poppet. 

Make your way outside, and dig a small hole for the jar. Once done, screw it closed, tying it to sealing someone's fate. Flip it and bury it upside down.
And as said before, don't go back to the hexing site! Especially after recently burying it. Only come back for the reversal.

To reverse the spell, pour out the dirty water and other objects inside, and cleanse the poppet of the negative energy.
