Card Care according to Llewellyn Publications:(This came with my Revelations Tarot Companion deck, by Zach Wong.)
--x Embellish the box you will be keeping these cards in (you will be provided with one if you buy any of the Tarot decks they've published) with protective and/or empowering symbols.
--x Wrap your cards in a protective cloth or deck bag.
--x Between uses, cleanse your cards by putting them upright and in order.
--x Smudge with sage to cleanse and re-energize your cards.
--x Store your dexk (in a safe place) with stones or crystals that absorb negative energy, promote healing, or provide protective energy.
