As I remember, the description that I read says you run your right index finger up to the top right corner of the page, then move the page over to the left where your left thumb takes it and feeds it to your left index finger (which is holding down the left side of the book). Finally both left thumb and index finger are holding the left side of the book, and your right index finger swings back up to the upper right corner for the next page. Hope this clarifies the method.
