I considered myself a desert mermaid for 16 years. Now I am at home by the sea.There are countless tales about mermaids, and some of the most popular are of Celtic origin. In some tales mermaids are more benevolent, and have the ability to grant the gift of magical powers. In other tales, their sighting was thought to be a bad omen, foretelling storms and rough seas. Numerous folk tales exist describing their interaction with humans. Here are some lovely turquoise mermaids swimming in a pale blue sea. The perfect tropical design for your bathroom.
