Use a dry surface to roll the rice paper. Fill a large shallow dish or pie plate with about 1 inch of cool room temperature water. Dunk one rice paper sheet into the water for about 3 to 4 seconds, or until it is just pliable enough to roll, but still stiff. (Read packet directions. Some brands require longer.) Transfer the rice paper to a dry smooth surface. Place the filling in the lower third of the rice paper. Stack the fillings on top of one another, leaving at least 1 inch clear on all edges. Wrap the rice paper similar to rolling a burrito. Pick up the rice paper wrapper from the end closest to you, and pull it over the fillings to enclose them. Then, fold both sides in towards the center. Roll the whole roll away from you so you end up with a log shape with the filling completely enclosed.
