The second item that came in my goodie box with the big smile was the book Fairy Gardens, by Betty Earl. Unlike Janit Calvo, Earl deals as much with the fairy part of fairy gardens as the garden part. I think I learned more about fairies from this book than I ever had before!
Did you know, for example, that most fairies are offended by a spoken "thank you." They respond better to shiny trinkets left just for them.
And the best time to connect with fairies is Beltane (the first of May) when the barriers between our world and that of the fairies is at its weakest. Nights with a full moon and the Solstices and Equinoxes are especially welcoming to fairy activity.
So have an open mind and create a welcoming fairy garden in a container or your yard. Who knows what magic might happen?
