They make fantastic storage containers for a variety of items. Let's face it...they add so much charm to any space. I like to store my coffee, tea, honey, nuts, etc. in them for display under my vintage kitchen cabinets.
You can use the same idea to display your vintage canning jars. Just secure a vintage zinc or a metal canning jar lid with ring under your cabinet with a screw, fill your jar, then screw into the lid.
If you don't have any Ball Vintage Blue canning jars you can simply use a new canning jar. You can learn more about where to purchase Ball Vintage Blue canning jars at: http://www.etsy.com/shop/uniquecozytreasures
