I use white plastic one-piece screw-top lids sized to fit either regular or wide-mouth canning jars.
Mine came from Lehman’s but they are often available at hardware or kitchen-ware departments, where they sell the jars. These are not for canning, but simplify storage in pantry or fridge. They are easier to handle than two-piece metal lids, don’t rust or dent, and clean easily. I’ve used them daily for years. — Lynn Nadeau
