Use air dry modeling clay to make ornaments for your fairy or gnome garden. I made a gnome, gazing ball holder for a large marble, mushroom & tiny bird bath. Imperfections in the clay can be sanded when dry & painted with outdoor paint & a sturdy clear coat.
Recently while showing property I happened across a neat surprise: a fairy house built on an old stump at the end of someone’s driveway. Instant enchantment! The door has a roof overhang above, garnished with a bird's nest.
