Thanks for the heads-up, though. We do keep our seeds in dated paper envelopes. Enough to plant our entire yard twice.
The only drawback is trying to stock enough canning lids/bands.
I’ve been buying them abundantly for years.
Look into Tattler reusable lids.
I have some I used on some applesauce one year just to try them out and see how long they’d last.
I set a couple jars aside for the trial.
Going on 12 years now and they are still working.
