Setting up a tarot table.

I don't think there is any particular way to set up a table. As long as it is sturdy enough not to fall over and not so dirty that it will ruin your cards, it's all good. Do as much or as little as you like.

If you're going to be doing any readings outdoors (in front of a shop, renaissance fair, etc.), you might have a small bowl of tumbled stones on the table. If it's breezy, you can use the individual stones to weigh down the cards.
