I got this idea from Dedicant: A Witch’s Circle of Fire by Thuri Calafia (if I seem to be using and quoting this book quite a lot right now, it’s only because I’ve chosen this to be the beginning of my journey. There will be more along the way, I promise.). You create colored cards, and “guess” the color on the back of each card. I plan on keeping track of my correct guesses as I go. Ms. Calafia recommends you do this several times a week. Here’s how I did it:
Take 15 index cards and cut them in half as you’ll need 30 cards. You can of course use whole index cards, but I have small hands, so I cut them in half. I have the same trouble shuffling tarot cards.
