One of my most recent Spirit Dolls was "The Guardian of the Flower of Life".
She wears its symbol within her necklace. It is considered to be the basic template for EVERYTHING...existence as we know it. All of the geometric forms including Sacred Geometry are found within it. It represents Creation and our Connectedness.
She also wears clay sculpted Blackthorn flowers, symbolic for "Hope against Adversity" and Protection.
Blues were dominant for the Throat Chakra and Communication. Yellows were used for the Solar Plexus and Self Esteem.
