Storing Jars Inside Jars to Save Space

I was trying to "unclutter" my house and this tip came to mind. When you save jars for crafts or food, save the smaller one inside the larger ones. This saves not only room, but lets you see the smaller one by their labels, should they still be one.

But also, you can store the larger ones in the back and you don't run the risk of knocking the tiny ones off reaching for the bigger ones.
N-JOY!
