I finally found a way to organize all my seeds. I put them in a photo box and then labelled the dividers for the categories that made the most sense to how we garden.
I use separate dividers for the normal stuff that we plant like peas and melons and squash and tomatoes and peppers, etc.

So far I love the system. Everything stays contained and I don't have to use rubber bands. The seeds I save, I just put in envelopes and file with the others.
Now that I have this and the seed viability lists, I can toss out the old stuff that won't last and know exactly what I already have so I don't re-order any more than I really need.
