We recently visited South Padre Island. We wanted to save the memory. We took a pickle jar & filled 1/4 with sand. Then placed shells we picked up on the beach & a parking ticket from the beach. Then wrapped rope round the top & burned with a lighter to distress. Then we painted the lid with Elmer's glue & dipped in sand. Pushed a shell down on top & left to dry overnight. In the morning blew off excess sand. Bingo. Memory in a jar. .
