Fairy dust, fairy dust, well it's not made of garlic, unless it was perhaps made by one of those mischievous European fairys. New world fairys are usually good natured but not above pulling pranks on people, and each other. Recently this question was posed to me, I was hesitant to say the obvious, and it definitely doesn't have any glitter in it, remember fairy folk are forest creatures, and for that reason they are concerned with conservation and abhor plastic bits being tossed around.
My reply was and still is "Hopes, dreams, ideas, strength, perfect moments,love,gentle smiles and noisy joy, long held truths, courage and whatever other good things you can find." Perhaps I will collect all of the above mentioned and even a few more things, put them in a pretty jar, place it on a windowsill, where it will be seen by all who pass by, especially fairys/
