We have fairy houses all around our place. Even gnome homes.
Knots in trees, hollowed out parts of trees, logs, rocks, you name it...It's out there.
Some we have built. Others were already here naturally when we bought the farm.
My girls and I have put together some while my husband would just watch thinking we are weird. Well after a while I even noticed him collecting things to help us in our 'fairy house construction projects'.
I took a broken 'toad house' and reconstructed it for the fairies...
Little spots in the flower beds and gardens. A few little things set up in the barn--just incase the fairies choose to visit during our lambing season. We have made nature trails throughout the property and every once in awhile we put a little house out there for them, or find something natural and figure the fairies have already moved in...
Our girls like to go out looking for the gnomes and there houses too. Find a low knot in a tree, or a hollowed out spot and they will say thats one of the gnomes houses...
