Shuffling your deck-
There are various methods of shuffling your cards, Im giving a few that I use. You can use them too or develop your way that feels right to you. You have to shuffle at the beginning of each reading. Shuffling can be simple like we do for playing cards for the rest of the day. But the first shuffle or the last shuffle should be this way, this helps the card to get mixed well and get neutralized and ready for the next reading.
All mix method-
The all mix method is where you put all cards upside down and mix them a lot, letting them get reversed also. Then put these cards back into a pack and now its ready for the reading. This method is quite a good one, which can shuffle the card well with reversed and upright cards perfectly balanced according to the reading.
Cutting the Deck-
You can cut the deck into half and put them into reverse position and then shuffle them to mix them well. This also is a good method but your deck should be shuffled well before placing half the cards in reverse. As if your deck is arranged few suits will be reversed while other suit completely remains upright. And we want a fuller reading which comes with randomly arranged cards.
Normal Shuffling-
This is the plain shuffling method that we do while shuffling the playing cards. In this method though cards should be allowed to drop, pop out, and arrange the way they have fallen. This way some cards will naturally get reversed and customized for the reading with that querent.
