I've been working on these for awhile: they are miniature cairns. These are a familiar sight in the area where I live - hikers marking a trail or making a little monuments to remember special places. We've made some of our own too on warm days down by the river.
The stones are made from polymer clay and permanently stacked so they can be a source of contemplation next to your bed, on your desk, or any place you want to be reminded how to find your way home.
They will be for sale in my shop very soon. I hope you like them :)
