I have been saving all kinds of seeds this year, and while I don't have enough confidence to instruct you in the proper methods of seed saving, I think I have figured out a pretty handy way of organizing my seeds.
Since I have a large amount of collected seed I went one step further. I keep all my collected seeds in small zip top plastic bags I found in the beading aisle. These fit perfectly in the trading card sized pockets which let me have 9 types of seed per page instead of just 4.
I also tape my plant tags to a sheet of card stock and slip them into a regular sheet protector in the same notebook.
