Use a rectangle of paper, 2x1 in proportion.

It is possible to make a tiny library of such little books.

The BOOK with the COVER (8 pages)
1 Valley fold the rectangle in half from bottom to top. Then unfold it.

2 Valley fold the top and bottom edges to meet the middle fold-line.

3 Valley fold the rectangle in half from left to right. Then unfold it.

4 Divide the square of paper into eight equal sections by valley folding.

5 Make the limited creases, by dividing squares on a diagonal.

6 Turn the paper over. And also make the limited creases.

7 Mountain fold the top and bottom edges, giving the form a volumetric view.

8 Now folding proceeds in the air. Valley fold the central point and bring the lateral edges, as though close the doors.

9 Drown the center of the top square, compressing lateral creases.

10 Make that for the following square.

11 Push the back side, stretching lateral walls.

12 Close the book, accurately by combining pages.

13 Valley fold a near layer, being guided by the edge of the pages.

14 Mountain fold the edge.

15 Open the book.

16 The result. Turn the model over.

17 Fold over and over the bottom edge and insert it under the corners.

18 Back view.

19 Books with a cover is ready!

The BOOK (10 pages)

1-5 steps coincide with the previous model. The sectoring of the sixth step differs.

6 Make sectoring.

7-8-9-10 steps also coincide.

11 Drown the center of the top square, compressing lateral creases..

12 Push the back side, stretching lateral walls.

13 The result.

14 Valley fold and unfold the triangles in half.

15 Inside reverse fold the side points.

16 Fold the internal covers along the existing lines, thereby making the lock of the model.
