In general, our rituals have the following flow:

Everyone processes to the hallway while the space is cleansed and blessed, introductions are made.
Each person will then process into the space where they are cleansed, blessed, and their higher-self invoked.
We cast a circle for protection and to separate us from the mundane world.
We call forth the guardians and elements of the quarters.
We invite our Ancestors to join us.
We invite the God and Goddess to join us.
We have a meditation and/or an act of power.
We have cakes and ale.
We then close down in the reverse order and then socialize afterwards.
