Napkin
My Nonna always had the most beautiful napkins that she would lay out for special occasions but they were only single use. As in, they were fabric, but each design was kept as a momento of the event that it was a napkin for. This napkin was used at the dinner of my University graduation. I'm clearing out each napkin set and just keeping one of each as a memory of the occasion because I'm sure you can imagine the hundreds of napkins my family inherited.
