If you are in need of some freezer organization, there is a free printable freezer label template available courtesy of Martha Stewart.
You can mark the date the item was frozen on to keep track of what needs to be eaten first.
There are a few colors available so you can color code meats, veggies, fruits etc…
Martha suggests using these 2×4 weatherproof labels that run $30 for 500 or you can get 100 of them for $11 and shipping is free on a $25 order.
I think if you want a slightly more frugal option, you could probably just order color copies from somewhere like Staples ($.56 per sheet) and just tape these labels to your bags. Seems like it might serve the same purpose.
