A Fairy House has sprung up in my garden.I helped the little people by providing the bricks and a broken slab of marble I found on the roadside. GD1 and GD2 did the rest (GD=granddaughter). The door actually opens.
The little people have informed me that fairies like natural objects--shells, feathers, plant leaves, nests, rocks. These are Tunisian fairies so I bet they like the flat marble roof where they can dance in the evening.
