A less common but very interesting way to use mason jars is to make it into a one-of-a-kind picture frame. The clear jars would be best for this, and by pouring olive oil (try to avoid the garlic kind — could get stinky!) in the jar with an upright picture, you can get a sepia effect and a new way to display your pics.
