Fake Stones

Give your garden an extra touch with these light and fake stones made from foam and clay. It's also a fun project to do with children.

The stones are made from a material I call "sandy foam". A combination of expanding foam and sand. More explanation about the material I used for this stones, experiments with it and all the possibilities, look at my previous Instructables: Flexible And Light Stone Material.

As basis shape I clayed stone shapes with "Model Magic" from Crayola. Make little balls by rolling clay in your hands, then press to create a stone shape.

For the sandy foam I used flexible polyurethane foam of Douglas & Sturgess. I used 0.10 oz of part A, 0.30 oz of Part B and 1.30 oz of sand. Mix it for at least 30 seconds, and add little amounts of sands in between.

Cover your work area with sand so you can lay down the stones to dry without them sticking to the surface.

Get some of the sandy foam in your hands and model it around the clay shape. It will be sticky, so wear gloves and in between you can sprinkle sand on your hands so the foam doesn't stick to your hands. It will also create a more sandy structure.

Lay the stones down on the sandy surface. You can cover them with another layer of sand, to create a rougher structure.

These stones match perfect with the flexible stone pots I made from the same material. Here's a direct link how to make the pots: Flexible Stone Pots.
