1. Basic shape of bookmark folding: First, choose a favorite square colored paper, fold it in half along the center line, and then fold it from one side of a vertex to form a triangle. The other will do the same, overlapping the outer corners of the triangle to the inner corners, with the same sides, and folding the lower sharp corners upwards to form a triangle.

2. Fold the details of the bookmark: the reverse side of the whole is folded in half along the center line, and finally the sharp corner is turned outwards. After unfolding, the corner is turned over from the middle to form an inner triangle, and the remaining corner is repeated twice.

3. Draw a label: Finally, draw a label in the blank of the second repeated action, and a bookmark with a label will be ready.

Bookmark is a kind of reading label, which is made of paper, electronics, plant leaves and metal. Used to inscribe the title of a book, usually attached to the upper left corner of the cover of an ancient book, sometimes with the book number, the name of the inscriber and the reading place. A bookmark is a small piece of paper sandwiched in a book to record the progress of reading. With the development of the Internet era, electronic tags are derived to record reading progress and experience.

Bookmark pictures are random and widely used. Even used train tickets and plane tickets can be used as bookmarks. In addition to graphic content, art bookmarks are often innovative in materials and shapes. Bookmarks are more convenient than folding books and do less damage to books, so they are a good way to remember page numbers.
