How do I cast, or create, a circle?
There are a million ways to cast a circle. For simple spells, we recommend either placing witch bottles at the four corners (North=Earth, south=Fire , east=Air, west=water), or simply sprinkling salt and water at the circumference and walking around the circle three time clockwise with incense to cleanse the space and build up energy.
For more complex rituals and spells we recommend doing what is mentioned about and calling out the Guardians of Watch Towers of the four quarters and invoking the God and Goddess, or whatever Deities you which to bless the circle.
