During Miami's dry winter season we made a paper mushroom garden in the front yard one afternoon.
We used mostly brown paper lunch sacks, but we had a couple of colored ones, too. Benjamin created the red one below, then used markers to color some cardstock and cut out circles of that to glue on as decorations:
We had just planted the last one when the boys decided we needed signs to direct people's behavior around the mushrooms.
Do Not Chop Down The Mushrooms! (by Benjamin)
Do Put Mulch Here and Do Not Chop Down, by Jonah.
Jonah also wanted it to be known that since they are made of paper, we Do Not Water The Mushrooms. Nor Do We Step On Them.
