I saw the thread on riffle shuffling, and thought I would share my special way of shuffling the cards. It's time-consuming, but it really mixes the cards well.
It grew out of a concern that the cards were not being mixed thoroughly enough between readings. I can't riffle shuffle poker-style, so this is a slow-motion riffle which does not bend the edges of the cards.
1. Divide the deck into two fairly equal piles.
2. Place the top card from Pile 1 on the table to begin a third pile. Stack the top card from Pile 2 on top of the third pile so it overlaps the card from Pile 1. It's a bit like building a brick wall.
3. Repeat the pattern until all cards are stacked in the overlapping pile. If the first two piles were uneven, split the remainder of the deck and continue.
4. Turn the complete pile on its side and tap the deck until the cards shift into an even pile. You're ready to either repeat the shuffle or read the cards.
I'm not sure if this is clear enough. Think slow motion riffle. The rhythm you get into when placing card atop card reminds me of counting the sticks in the I Ching. It's a good space of time to focus and form your concept or question.
Anyone want to try and see how it works for you?
