Concertina or accordion book as a booklet
This booklet is a concertina with a small reinforcement
on the inside, so you can display it nicely on a flat surface.
It holds 6 photos sized 10x15 cm, but you can also stack two smaller photos below each other. Or you could stack a smaller photo and add text below it.
It is possible to foil press names, a date and/or a heart on the front side. And a little surprise, like a heart, can also be foil pressed on the linen reinforcement on the inside.
A smaller size featuring 6 photos sized 10x10 cm is one of many possibilities.
