Making a Pentacle/Pentagram Grid
A symbol of a star encased in a circle (Pentacle), or just use the star (Pentagram). The star is always made with 5 points, each has its own meaning. The upward point of the star is representative of the Spirit. The other four points all represent an element: earth, air, fire, and water.
Creating this type of grid is especially helpful for balancing energies in a home or work place.
