Take your tarot cards and hold them as a deck in your non dominant hand (the hand you don’t write with). Then knock on them once with your other fist. Then touch the corner of every card. Next fan them out, facing you and bring them close to your heart. Then you say an affirmation of your choosing. Something like this;

May my readings with these cards be true and accurate. May these cards bring blessings to all I read for and may I have confidence in all my readings.

You can make up your affirmation yourself but the above is an example and pretty much what I used. You re-cleanse your cards if they stop working or you want to remove negative energy off them, also just if you feel like it. How often you cleanse your cards is up to you. No need to put them under the moon because they might get wet or soiled which will ruin your cards but you can leave them on a windowsill inside if you really want to.

Storing your cards, you can store your cards in the box they came in or you might choose to wrap them in silk. I have heard of a lady who stored them in new make up bags. I store mine with rose quartz that I have charged under the full moon to absorb any negative energy off the cards.

I hope you enjoy your cards. I am still learning to read the cards, I just started in January! Read your cards for yourself and others as often as you can
