I have always worked with the children all each having an individual folder (plastic with easy plastic sleeves in).  These folders stay in the room and go with the child on Graduation Day.  I try and purchase the plastic folders that actually have a plastic sleeve at the front so I can slide in their photograph. This makes the books very recognisable.

The folder can have the extra art work they create (at play time) and anything they don’t want to take home during the session and put on the Goodbye Table.  I also take photos during the morning over the years and I print these off and put them into the child’s folder.
