If you are like me you just toss the inner bag from your cereal boxes without a second thought. What could you possibly do with them anyway? Well, I have recently discovered that they can be used in a variety of frugal ways.
First, you will want to rinse the bag out and let it dry. Then, you can cut the bag at the seams and open it up. Use it in place of waxed paper in non-baking applications like putting no-bake cookies on it to cool.
Another idea is to use the bag for marinating meat like in the picture above. No sense wasting a brand new bag when you were already going to throw the cereal bag away. You could also put breading in the bag for coating chicken or fish, etc.
I just did a quick search to find more ideas for re-using these bags and found an article with many ideas. Check it out here. Maybe these ideas will save you a little money while helping out the environment.
