saw this somewhere out there on the interwebs and can't remember where, or i'd give attribution. anyway, it looks like such a fun thing to do! and i want to try it. i wonder if the moss on the trees around here would work, or maybe i could find some at a garden nursery. so now that i've put it here, i might be able to find it when i'm ready to try this! if anyone tries this, i'd love to hear about it and see photos... ok??
and i'm not advocating anarchy, so don't get your knickers in a knot.
