Select blank and light paper, cut it into 7cmX5cm, and fold it in half. The same size, choose a little harder paper (cardboard or coated paper) to cut a little, as the title page. It should be noted that paper has its fiber direction, so it is best to use the natural bending direction of paper (perpendicular to the fiber direction) as the direction of page folding, otherwise the finished book may roll up and down to the middle if it is left for a long time.

Clip 15 pages (or any number) together with two title pages at one end and one end, and pay attention to check the opening direction of the pages. Apply glue to the spine (or many people didn't check it well in front), then apply glue to the spine a little bit, and then apply it to the other side. Put it under a heavy object and press it. Don't press the sticky part.

Select cardboard with appropriate thickness and cut it into 3.6cmX5.2cm (the upper and lower sides and open sides of the book are larger than the number of pages1mm); Choose cloth or tough paper and cut 3cmX7cm as the spine; Decorative paper is cut into 4cmX7cm for book shell decoration, and each book needs two pieces.

First, mark the spacing of 1cm on the book, that is, the thickness of the pages, and stick cardboard on the covers on both sides of the spine; Then paste the decorative paper, which covers the spine 1-2mm, cut off the extra two corners and wrap the cover. The book case is finished.
