Nice! I wish I could start peppers and tomatoes from seed. Since I can't, no point in saving them. Right now all I'm saving is beans. I'm on my third generation of pole green beans and my first generation of cannellini. So exciting to take in the harvest when it's yours from start to finish! I got very few pole limas last year, plus I had some purchased seed left from the year before, so next year will be my first year planting limas entirely from saved seed.
I keep meaning to save squash seed. Not sure why I've never got around to it. I've done quite a bit of hand pollination in those couple of years when the bee population was so frighteningly low, so all I would need to add is isolating a few flowers. Maybe next year ....
