I shuffle 3x3 and use reversals ie.first, reverse part of the deck, pick up part of the deck (from the bottom of the deck) with your hand, lets say right hand from your other hand (left), the right hand gently throws three separate sections of the cards to your left hand, with the last one being all the cards in your right hand. I then repeat this two more times including two more reversing of part of the deck. This concludes the shuffling.
Then with my left hand, I cut the deck once from the top of the deck that is in my right hand, and put that on the bottom of the deck. This gives me the first card on the top of the deck as the first card to lay out (positional or free). I then cut the cards another time, lay those to the side ie no longer part of the reading, so the card left on top of the rest of the cards in my right hand is the 2nd card. I do this for as many cards as I need or planned to use. Using this method, your left hand should not select too many cards to cut and lay aside, because you would run out of cards lol.
