Most things are simple once you think of it. This one is embarrassingly simple but if you are like me, you like to over-stuff everything.
If you over-stuff a freezer bag you have to use fewer of them, right? That may be the case but you will also use more freezer space and end up with a frustrating mess.
Fill your quart-sized bag with about two cups of your freezer stash. Two cups is a good amount for most recipes. It will already be measured for you. In addition, your bags will actually stack.
When your ingredients are still fresh, fill the bag and then flatten the contents. You will have an orderly stack of food in your freezer which is more likely to stay neatly stacked through the winter.
