My favorite are these 1/2 gallon freezer jars. They are perfect for storing beans and rice, and they look good on open shelves. I always freeze my dry beans for two weeks after purchasing, and so far I haven't had any trouble with bugs hatching out in them.
These jars, a throw-back to the old cracker jars, look really nice on the shelf. My main problem with them is the threading on the lids. It is hard to get the lid back on once you take it off. I have an old jar, an original, and this newer one here that I keep my oatmeal in. If the threading was better, I'd have lots of these jars!
For behind pantry doors, I like these cereal storage containers. They are inexpensive and you can easily get a couple of boxes of crackers in them, or several bags of brown or powdered sugar, and of course they are perfect for cereal.
I'd love to hear any of your ideas on kitchen storage. I'm constantly trying to find ways to organize this small room!
