Saving Tomato Seeds

Well, I've never done this before, but I remember seeing my Dad dry seeds like this. These yellow cherry tomatoes were spectacular in a very bad tomato season, so I'm trying it. I also bought a perennial Hibiscus yesterday on sale--now is the time for garden center bargains! Lowes says they will have some fall seeds in around the second week of August. They are the only source I have found locally who restock for fall, and fall is my favorite season in the garden: lettuce season!
