Basically as mentioned in a previous post, I PR with my leg crossed and the book resting on my thigh. As far as page turning, with my right hand, I use the top first section of my index finger. Sometimes the middle of that section or I use the cease of that section. My thumb slides upwards in contact with the page as my index finger moves from the center crease on the top left of the page over to the top right of the page in a clockwise motion. Once at the far top right of the page, the top crease of the index finger lifts the page then, I use the little finger to continue turning the page over. Works Great!!!! Turning a clump of pages at a time is kept to a minimum if any. I hope my technique helps.
