Fill your jars, while still hot place a waxed disc over the pickle, then a clear (cellophane) circle over the top of the jar, and secure with a rubber band. As anything with vinegar can get through the clear top it's best to put a metal lid as well, over the clear cover.
Firmly secure lids and process all jars in the canner for the time specified. Test to see if jars have sealed properly by pressing on the center of the lid, which should be slightly depressed. Any jar that isn't sealed should be stored in the refrigerator and contents should be eaten in 2 to 3 days.
