New Keiki - I think you need to have some air movement in and out of the bag or mold/mildew etc. develops in the stagnant air - I've only tried this once myself and then only half-heartedly. Maybe Cynthia will "weigh in" shortly and can give us all the minute details - as she utilizes this method. mike
