Hi Sue
For faire work, I recommend all of the above suggestions, as well as, ground and shield, ground and shield,
GROUND AND SHIELD!!!!!!
I realise that you probably do this anyway, but when working a faire, you might want to put some extra "Oomph!" into your shielding.
You will be:
Working in a spiritually 'active' spot.
Working in an environment with many different folks, and their concommitant energies. These run the gamut from refreshing and wonderful, to the equivalent of psychic sewer sludge. (Rare, but I've felt it. It may not be your client, but some poor unfortunate who just happens to be there.)
Hopefully, doing a lot of readings. Grounding can really help prevent burnout, especially if the clients come in a steady stream.
Shielding keeps those energies balanced, because when you're working in large public places, there seem to be some weird ebbs and flows sometimes. At least, that's what I've noticed!
All the best, dear Sue!
Tell us, please, how you make out!
