These are pallets of pebbles at American Soil stone suppliers in San Francisco
Although they are all neatly arranged in their display cages they can wait to get out and back into the real world.
Here's the man who knows how to arrange these eager pebbles in a uniquely decorative way each time. His name is Kevin Carmen. His website is http://www.kevin-carman.com/
Kevin is working on his project too here along with the rest of us in Gualala California this week.
Here's a taste of what Kevin is doing with the two pallets of 'blue grey skippers' he is working with this time.
I won't spoil the end result by showing you too much more until the work is completed hopefully by Saturday.
