I meant we leave all the jars in the canner after preheating and only take one out at a time to pack the jar and then place it back in the canner before we get another jar out. That way the canner is always full minus one jar.i was putting them in one jar at a time. It fell over when putting them in. One jar tipped and it was like dominos from there. The quarts have been fine, but the pints were a pain. I wish i could find a better rack for the canner. It looks like the newer canners have a rack with more wire.
