I read that it is best to store flour in the refrigerator to protect it from bugs. I purchased three Rubbermaid containers and put the three different types of flour I use in them. I put them along the back of the bottom shelf. There is plenty of room in the front of them for other items.
I don’t know about you, but I seemed to lose leftovers in the back of that bottom shelf. Another place that food items hide was under the meat drawer. I now keep the extra flour under there. I have room for three packages.
It worked out so well that I started keeping my corn meal on the bottom shelf also.
