>> seeds for my Butterfly Pea vine. The seeds got moldy so I had to dump them. I've still got seeds from that plant in an envelope
Lin, I agree with you. That is super important. Any seed has to be really dry (fully air-dry no matter how long it takes) before you seal it inside plastic - even if the plastic "breathes". Like you, I use paper envelopes to let them dry for weeks or even longer.
Folding the flap down and securing it with a paper clips keeps them from falling out if the cat knocks them over. And I can write the name and date on the envelope. I save return envelopes from bills that I get in the mail. You can let entire blooms continue drying inside some big envelopes.
Usually I print labels on the laser-printer at work to get fine print that isn't blurry and won't run when damp. Then I put the label inside the Ziploc (or pill bottle) so the Scotch tape can't fall off or be pulled off. It makes it easy to transfer the seeds AND the label from one container to another: I just pour the label in along with the seeds.
