I assume that most of the ideas in this podcast are for large seeds. I deal mostly with gesneriad seeds which are almost as fine as dust particles. I store my seeds in white tissue paper, multifolded to produce a small 'pocket'. I gather my seeds on a white piece of white typing paper where I clean the seeds of chaff and debris. I then fold the piece of paper and pour the seed in the pocket and fold it close. The pocket is then placed in a 1-3/4" x 2-7/8" glassine enveloped like those used for stamps collections. The glassine envelope is then placed in a #3 coin envelope and labeled with the seed's name. The coin envelopes are then place in an air tight plastic container with a dessicant pack and stored in the bottom drawer of my frigde. Some of my seeds are over 14 years old and still as vialble as the day I collected them. I do agree the seeds should be very dry before storing. Lucky, with gesneriads, they usually dry thoroughly in the pod before they're even harvested.
