Fairy houses, in case you are late to the party, are small whimsical dwellings made of natural materials, like drift wood, sticks, bark, shells, acorns and feathers. They, of course, are for tiny winged creatures to enjoy -- and for children to build. (Legend has it that kids would construct these diminutive homes so that fairies would watch over and protect them.) While you can surely build your abode wherever you please, we hear that fairies prefer to lay their heads in a crook or stump of a tree, in the woods, in a flowerbed or by a creek. To get your kids into the idea, pick up (or check out) a copy of Fairy Houses by Tracy Kane, which includes a section about building your own.
