This is a very interesting discussion.
I was quite interested in how different people packaged their seeds.
Packing seeds for my box at home is different than packing for a seed swap, that box is jiggled and tossed daily for months, so any seed that can get out, will get out!
for paper, would I just fold some printer paper? How would I fold it? Would I use tape? If no tape wouldn't they get out?
Origami sounds too time consuming, but fun.
I did a 1 minute google search, I could get 1000 1 3/4" x 2 3/4 ' ( " is inches) glassine envelopes used by stamp collectors for $36 (this seems good, glassine is actually paper so moisture would not be trapped and should not get static electricity). But the glassine envelopes do not have any adhesive, would I use tape or just fold two or three times?? If I used glassine then probably I would not need the plastic?
