In case anyone looks at this thread for ideas, here's what I ended up doing:
In my over fridge freezer, I cut down two boxes that, luckily, fit perfectly on my bottom pull out shelf. I totally removed the top of each box. Then on the side facing the front of the freezer, I cut away the top 2/3.
In one box I put all my ziplock bags of homemade sauces, soups, and gravies (I freeze them in ice cube trays for easy portioning.) In the other box I put all my other homemade stuff--cooked rice and pasta, nut and rice patties, uncooked bread balls, etc.
Between the two boxes the bottom of the refrigerator shelf is oddly shaped so I will have to be an architect to design a box that goes there. Currently in that spot I have a 64 ounce glass storage filled with homemade broth ice cubes. In that area I also have 1 qt mason jars of frozen grapes and one of diced red peppers.
On the top shelf of the freezer I have ziplock bags of homemade tortillas, freezer packs, a glass jar of flax meal (for our smoothies) and a few other items. All bags of purchased frozen produce are in the doors.
In my 4' tall freezer: The top shelf is for all my gluten free flours. One is in a giant glass jar, others are either in quart mason jars or ziplock bags. The next shelf down is mason jars of home cooked beans (I froze them on cookie sheets before putting them in jars so I only use what I need) and grapes. Plus bags of purchased mango chunks. Next shelf down is bags of whole tomatoes, red peppers, and misc. The bottom shelf is ziplocks of grapes and other produce. The door shelves hold purchased produce.
The canning jars really organized stuff. However, they do take up a lot of room. The boxes in the freezer helped the most. I saw wire baskets that were $15 each. I already had the cardboard boxes. I'm really please with this. I'd like to put more stuff in more jars, I just don't know that it would all fit.
