There is not much to saving seeds, Anne. First, only use seeds from ripe fruit/veggies. Place the seeds on a paper plate or paper towel and set them in a warm & dry environment. Humidity will cause them to go moldy! Once they are throughly dry (takes 7-14 days) place them in an envelope or some kind of container with a tight lid. I put a desiccant packet in the jars or envelopes (save them when I get them in things I buy) and store in the fridge. You can also buy seed saving envelopes and desiccant packets online. Got mine from Amazon.
Note, this is not the best way to save tomato seeds. Follow directions Connie posted.
Hope this helps.
