Last fall we had our 4th (or was it 5th?) hypertufa party. In case you've never heard of it, hypertufa is a mixture of portland cement, vermiculite (or perlite) and peat moss. It is used to make containers for planting, or in my case - mushrooms! Anyhow, here's my share of the haul - 7 mushrooms and 3 planters. The mushroom caps were molded over a cereal bowl. The tall containers were molded over a popcorn bowl and the shorter container was molded over a round serving bowl.
