I shuffle then pick cards randomly from the stack. If I'm reading for someone else I either get them to shuffle and pick or I shuffle and I fan the cards out for them to pick.
I shuffle the deck, hold it in my left hand, tilt the cards toward my right hand and let part of the deck slide into my right hand. The top card in my left hand is the card I pull to read. I put the cards in my right hand at the bottom of the stack, do a short overhand shuffle and repeat the process until I have drawn the number I need for the spread I'm doing. So, basically, I just let the deck decide where to separate.
I like this idea! Gravity and friction do the fine-tuning after the shuffle.
As a novice I wondered if you could offer me your wisdom on how you select your cards?
