I just thought of something else, possibly better than rocks. Seeds, soil, and inherent spirit therein. That is planting something, and nourishing it. This does not mean taking it home, but finding an area within the area, the Cairn if we do indeed do it there (I get the distinct impression that they would really like it, even from the distance of Halifax), and plant something people think will benefit the Fae, and can be used by those around, again encouraging that energy flow.

This is not to say that we shouldn't do something involving rocks, and their spiritual essence/intelligence, just not necessarily at this workshop. I'm setting myself up for two again, aren't I?
