I have been making these since I was 13 years old, as they were a project in my high school's greenhouse club. We would make them and enter them in the Philadelphia Flower Show. I still love making them as much as I did back then, and you will, too! You will mix a wet batch of a clay-like cement mixture called hypertufa and mold it into a faux-stone vessel. It will look as though it has endured centuries of weather. Bring gloves & and wear old clothes to this fun, but messy, project. Pick up in three days after the concrete has set. Upgrade with a selection of succulents to plant in it.
