A fun way to preserve special summer memories is by using a tin lunch box. You can find them at craft stores and they come in various shapes and sizes.
Use permanent markers and stickers to decorate the outside then use a clip magnet on the inside cover to hold all the photos. You can make a booklet with your photos or just stack them together and secure with the magnet clip. Put souvenirs, postcards or other memorabilia inside.
You can also use a tin box you already have and paint it.
