Wipe gently with a clean soft cloth before you begin. You do not have to use 'spooky lighting' or candles. It is best not to play distracting music. As spirits love flowers - you might want to place some in a vase of water near the area in which you are working. Spirits also love water - as they are part of the collective unconscious which is the flow of water.
Some people like to say a prayer over the board - or do some other ritual.
Use a protective white light of energy to surround yourself, the board, those you are working with, and even the room. This white light is created by you in your mind. Decide if you want to place the board on a table, upon the knees of two persons, or where it is most confortable for you to connect. You can work alone or in a group. If you work with others be sure they are not negative in their thinking.
