Striving
Like JSU, I also fold a couple of millimeters of film, but I fold to the shiny side, not the emulsion side. I do this because the take-up spool rotates counter-clockwise when looked at from the bottom of the camera, and folding this way creates a nice hook that secures the end of film inside the takeup spool. Folded this way the hook is also bent away from the shutter curtain, but I also have no difficulty in stopping during rewinding as soon as the film end has left the takeup spool.
