Make a tiny booklet

First fold a square (origami) piece of paper in half. The smaller the sheets, the smaller the booklet 😉
I took 7 sheets of 15 x 15 cm white paper. (= 5,9 x 5,9 inch)

On the fold line, tear the sheet in half.

Then fold the two sheets in half lengthwise.

And fold the double-folded sheet in half width-wise.

Then fold the bottom to the top.

Turn the sheet over and fold the bottom to the top as well, it will look like as you can see in the picture below.

Do this with each of the thirteen sheets. We don’t need the fourteenth, because we need an odd number.

And fold all the sheets together into one big harmonica. Pay attention to two things:

1. Slide them together in the right direction.
2. Make sure the open side is on the back.

The next one you slide exactly the other way around and that’s how you slide all the leaves together.

To a large harmonica.

We fold the harmonica together and hold it together with a clothespin or a big paper clip. The filling of the booklet is ready and we will continue making the cover.

Take a nice origami sheet with print or with a solid color. This one is also 15 x 15 cm. ( 5,9 inch)

Cut the sheet in half.

We are going to cover the book like you cover a regular book. Make folds around the filling so you know how big it should be. See pictures below.

Draw two triangles where the back of the booklet will be and cut them out so you can fold it easily. On the top as well as on the bottom.

Fold the top and bottom inward and then the sides as well.

Now slide the first sheet of the harmonica filling into the cover.

And slide the last sheet into the cover on the other side. Now you understand why we use an odd number of sheets.

You can also clamp it for a moment to prevent the leaves from sliding apart.
