I noticed some discussion in this thread about packages in which to store seeds.
Just thought I'd mention that glassine envelopes are a terrific way to save seeds - the best I've found so far. They are sealed up tight by simply folding the end over twice and adding a little piece of tape. As the paper has a slick feel to it, the tape can be removed easily to open and reseal the envelope. You can write the plant name on the package with an indelible Sharpie, which works great.
The people who organize and distribute the vast amounts of seed that are donated to various clubs in annual seed exchanges seem to appreciate getting seed in these envelopes, as they are easy to handle and avoid the drawbacks of paper and plastic envelopes. I find that paper envelopes, whether bought or homemade, always seem to let fine seed leak out the seams and corners... unless they are painstakingly taped up (I don't have that much patience!) Plastic envelopes, e.g. the little ziplock ones, are static-y, which can also be a problem with fine seed and fine chaff, which sticks to the inside of the envelope.
I've used the glassine envelopes for some time now, so I'm not up-to-date on what other options might cost. The glassine envelopes seem pretty cheap - I get them for 3.5 cents each ($35.00 US/1000) which lasts me a few seasons of seed collecting, or $3.70 US/100.
Anyway, just a thought in case it's helpful for any other seed collectors.
