I am pretty sure that everyone has seen this kind of pocket accordion book before. It’s simple enough for children to make: take a strip of paper and fold one long edge up to make the pockets, then fold the strip into an accordion
There is an easy variant if you are using a fancy paper: fold the top and bottom edges of your paper to meet somewhere middle-ish, then fold your accordion.
I have come up with yet another variation. This one is related to a boustrophedon and gives you twice as many pages.
Fold your paper in half vertically, open flat, then fold a strip on each side toward the middle. The turned in strips on the sides should be the same width, and deep enough to work as pockets. I started with a 30.5 cm (12″) square and folded in about a 6 cm (2.25″) strip on each side.
Fold your paper in half horizontally as shown below. The pointy finger indicates the fold at the top.
Fold the bottom edge up to the top fold, then turn your paper over and repeat with the other side.
Open your paper up, but leave the side folds turned in. Cut up the central fold line through the bottom three sections. Do not cut the fourth section. Reverse the fold at the green pointy finger in the fourth section.
Your accordion will look like this. You can see there is a gap in the middle. You can leave your accordion like this and it will work fine.
If you don’t like the gap, you can use adhesive (glue stick, paste, double-sided tape) to close it.
Now you have an eight page and eight pocket accordion made from one piece of paper.
There will be more pockets tomorrow.
