Pretty sure this is not an original idea...but it Works for Me!
Recently I took an inventory of what was in my freezer(s). Anything that was in the deep freeze was written in blue, anything from the refrig/freezer was written in black. I keep the list posted on the side of the frig. and we are good to go! Now I can see quickly what I have in stock, and if there is any need for replenishing. It also helps so I don't over-buy a certain frozen product. (Of course it doesn't seem to be working for the purchase of ice cream goods...those just keep popping up in there! hehe)
Hope this helps organizing your freezer goods!
