Picture a little cluster of toadstools at the foot of a tree. Red caps, white spots, a bit of moss.
Now picture them made of concrete, so they last for years.
Cement mushrooms look magical but they are surprisingly easy. A bowl, a cup and a bag of mix is really all you need to start.
Here are 10 cement mushrooms DIY ideas, from basic casting and silicone molds to painted toadstools, big statement pieces and tiny fairy garden sets.

Good mix makes all the difference. You want it smooth, like thick yogurt.
