A witch circle is a circle drawn or made by a witch as a safe place and energy-channeling cleansed area to perform magick. It acts as a portal to the realm of deities and spirits, as a protection from evil forces, and a sacred area to help you focus. It can be drawn with chalk or charcoal or pencil, built with twigs or rocks, made with salt or rope, or even made with tape. It must be completely closed to work, or evil spirits may be let in and it won't be protective anymore. You can draw or make a pentacle in it if you are pagan or believe in that, or it can just be a simple circle
