This is how I save seeds. I call it my "seed tray." Every year late summer until first frost I pluck a few from the garden and throw them in here to dry out. These are some from this year: sunflower, zinnias, marigolds, love lies bleeding, mallow, beans, peas ...
Here's one from years past.
Although this method has worked for me just fine, this year I am taking it one step further - I'm actually storing my seeds more properly in this nifty Michael's special box that I keep on my library shelf. I found these cool little bags at work and took them for myself. I have one of these boxes for all my plant tags, too. (Maybe I have a sickness.)
And this is what bloomed from that spirit ...
