3. Postcard Tray
I wasn’t able to find where this idea came from but thought it would be a fun way to use your postcards. Find a tray and place your postcards on the tray. After placing the postcards find a plastic covering. I was picturing something like this. It is a plastic covering that is sometimes seen on dining tables for extra protection. The nice thing about these plastic coverings is that it is heat resistant up to 160 degrees, which would be perfect for serving hot plates!
