Folding is the toughest part. Fold the bottom corner over the stuffing so that it covers it completely, with the tip of the corner now pointing to the center of the egg roll wrapper. Fold in the left corner, followed by the right, so that you now have formed an envelope. Roll the wrap upward one time, leaving the top corner open. Wet your index finger in the small bowl of water and press to moisten the top left corner. Now fold that down on top of the filled roll and press lightly to seal.
