You have probably seen the mason jar lights, but have you seen a mason jar used for a terrarium? I remember my mom canning peaches in mason jars. Who would have ever guessed that they would become such a popular commodity for decorative purposes. I personally like the Mason Jars because of their nostalgia, light blue tinted glass, and their classic design. A few of my favorite uses for the Mason jars are the drink dispenser, terrarium, and the outdoor path light.
