Vintage Blue Mason Beach Memory Jar

I am blessed to have a small collection of vintage blue Mason jars from my paternal grandmother, my Meme.  Most of them have their original tin lids and are in perfect condition.  I display them all over our house and am constantly changing out the displays.  Every time I help host a bridal or baby shower, the jars come with me to add a bit of vintage flair to the decorations.  After our recent beach trip, I decided to add to the beach memory jar I started a few years ago.  It is a simple and affordable way to preserve our special finds and remind our family of our amazing travels.  I filled the bottom of the jar with the pure white sand of the miracle strip of beach we visit in Navarre Beach, Florida.  It looks like sugar and reminds me of one of my favorite places in the world.  Next I carefully drop shells into the jar one by one.  I use the tines of a fork to arrange the shells.  It is a bit tricky to get everything positioned the way I want it, but worth the effort.  I love that I can easily add to and rearrange my little collection with special finds after every trip.  

How do you preserve travel memories?
