1. Print photos onto paper in a size about 1 in. smaller all around than the interior measurements of jar. (Do not use original photos; photocopy or scan and print them to avoid damaging originals.) Trim as needed.
  2. Use card stock and glue stick to mat photos with a ½-in. border showing around the edge. Let glue dry.
  3. Carefully insert matted photos into jar back to back.
  4. To help the photos conform to the jar’s shape, roll up a small piece of card stock and place it between the matted photos.
  5. Screw lid onto jar. Tie twine or ribbon around lid rim.
