When I go to my various fire circle gatherings, many of us collect a bit of ash from the sacred fires to bring home. I have a friend who hoards empty film cans and then hands them out at the end, much to many people's delight.

I have collected many, MANY things over my life. (thanks, Mom!) Now I seem to have settled down to masks and Goddess images. The masks have to be local creations with some significance, not just fancy ones with no meaning. And the Goddess images can be 2-D artwork or a 3-D figurine.
