If you know how to read tarot cards or wanting to know how to read them, then this is a great art exercise for you. Here is how you can use tarot in art.
First get your deck and shuffle your cards.
Choose one card, however you usually choose, pick on off the top, pendulum, fly outs ext.
After you have chosen your card, sit with it and meditate on the meaning of the card you pulled.
Get any art materials you like to use.
Draw or paint what you feel is the meaning of the tarot card to you. Don't just try to copy the art on the card, really look at the card and focus on what the card says to you.
