Fall is a great time of year to get outside and enjoy the magical colors that mother nature is providing. While there take a look around for a Fairy house or 2. IF you cannot find one then think about creating one. The base of a tree or interesting root structure can be a great start. Moss, Pine-cones, acorns, leaves sticks all make good building materials. Please use only those things that you find on the ground. Do not peel Birch Bark off trees. This is a house we built in Maine this summer.
Some areas of the country including Maine have actual communities of Fairy Houses that you can visit. So get out there in the next month and search for or build a Fairy House. My kids young and old have always been fascinated by the Fairy/ natural World.
