One of my absolute favorite natural items to work with are abalone shells. They are so gorgeous! I love the different colors and the iridescent shine to them. My grandma turned me onto abalone as a small child. She lived in Arizona, near Apache Junction, and she used to send me all kinds of Native American abalone jewelry that she's buy on her frequent trips to the reservation. Abalone shells are versatile - you can use them for smudging, burning incense, as offering dishes, build little fairy gardens in them or set them out purely for decoration.
