I use painter's tape and a permanent marker to label things.
I have two freezers and two fridges.
The upright is:
top shelf - work lunches for DH, smooshed bananas (premeasured for muffins), and this is also my "misc" shelf
second shelf - containers of leftovers
third shelf - berries/fruit, french fries, perogies, shredded cheese
fourth shelf - meat
bottom shelf is a drawer for frozen veggies
The chest freezer:
brown sugar
hamburger (cause we have like 17 packages)
homemade applesauce
oatmeal containers
overflow like extra berries
garage fridge:
The fridge is for large containers, extra milk, extra eggs, etc.
The garage fridge freezer is our bread freezer. I buy bread, bagels, and the like from the bread store and it all goes in there.
Fridge in the house:
The fridge is for small containers of open things.
The freezer is for small amounts of flour, sugar, and the like.
Eventually, I want to get the fridge freezer in the house all cleaned out. The goal is to make a trip out to the garage once a week and haul in all the items planned for meals for that week and put those in the fridge freezer. In that same trip, I would gather the pantry items needed and they would go in the cabinet that food goes in in the house. But, I just haven't gotten that organized yet.
I also write stuff on the calendar also. I use Outlook for everything. I have meals planned out through the middle of April. When I toss something in the freezer, I go to the end of my menu and add it on.
