Seed Ambassadors' Seed Saving Zine - 4th Edition
Seed Ambassadors' Seed Saving Zine 4 hand out (3.8 MB PDF) This handout formatted version is your best choice for printing and reading if you do not have one of those fancy zine staplers.
Seed Ambassadors' Seed Saving Zine 4 duplex (3.5 MB PDF) This zine formatted version is for printing in a duplex printer and folding into a Zine. That is why the pages seem to be in a weird order. If your printer does not have duplex ability you can print it one page at a time, flipping each page over to print the back side.
