^^ creating a board would be best, you can charge it with energy and make it to reflect your beliefs, like carving faeries in it if you follow faerie magic.
the obvious casting the circle, if you can, get some sage smudge so after using it, you can cleanse the space just in case a spirit decides to hang around. when using the board, make sure your fingers are not on the planchette [pointer thingie] they have to be lightly touching it, or resting slightly above it. when the spirit begins to move it, you should feel your fingers being sucked to it, like holding two magnets slightly apart. as well, if the spirit is channeling through you, it's common to hear/feel the response before the planchette moves.
above all though, don't upset the spirit. be respectful and nice, do not yell at it, argue with it, or curse it out. bad things can happen. exceptions though can be made if you know the spirit, but first meetings, be nice, you don't want a vengeful spirit.
