Thank you!
I don't remember who I learned it from, but it sure saves space and protects the seeds from my cat, and from me knocking the plate off the table.
I have a couple of other articles creeping along towards readability, about using desiccants to get seeds dryer than household air.
According to my little blue-pink humidity cards, and inside my house in my climate, the average jar of seeds stays around 50% relative humidity, which is barely enough for short-term storage. I wonder whether people who keep seeds viable for 10 years live in drier climates, or keep their houses warmer?
