The Summer Solstice, also known as Midsummer or Litha, marks the longest day and the shortest night of the year. Since ancient times, people have gathered to celebrate the summer and honor the Sun. The days are warm, the flowers are blooming, and light reigns. Summer Solstice has also long been associated with fairies, those strange wee folk who play tricks and give gifts, according to their moods. (Think of Shakespeare's Midsummer Night's Dream.) Therefore a good way to celebrate the Summer Solstice is to make a fairy house. Construct a tiny house out of anything you want — paper, twigs, leaves, cardboard, even plastic. Decorate it, furnish it, and hang it in a tree or hide it in a bush in your yard. Put an offering of tiny cookies or seeds in the house. See if the fairies gather. If they do, will you let me know?
