Every year our family either makes or buys a special Christmas ornament that commemorates something special that year. Like our first trip to the beach as a family we made a clear globe with actual sand from the beach. We poured resin into it and let it dry like the water on one side, then added tiny shells on top with the date.
I found a cool site the allows you to design your own glass ornament! This year I made a “A Thrifty Mom” glass ornament, and had the date on the bottom that we started. Just click the Personal Creations logo
