I have always loved this idea but have never managed to get one going. In the past, Orion would set something on there for a few minutes, tops, then it would end up somewhere else in the house or back outside or crumpled up, or whatever. Which is fine. Who am I to tell him how to experience nature? But I am enjoying it now that he is "into" the idea. He wants to look for stuff on walks and decide where to put it. He still decides to crumple up alot of the leaves when they dry or take a hammer to the various pod type things, but this is the first time this much stuff has actually up and make a pretty display in our dining area!
