Drop 13 rose thorns into a jar or bottle one-by-one.
As each one drops say “Evil presence I banish you”
Cover the thorns with the petals from one rose.
Fill the jar/bottle 2/3 of the way with salted water.
Leave the jar/bottle open and unattended overnight.
Before sunrise close the jar/bottle tightly – evil will be trapped inside.
Wrap in dark fabric and bury it far away
