Classic origami triangle bookmark
The making of this origami bookmark is a classic. The first thing I learned was how to make this origami bookmark. Although this origami bookmark is relatively simple to make and classic enough, the biggest charm of the origami bookmark is that it is easy to use. However, it has a slight disadvantage, that is, this origami bookmark cannot make the page numbers we marked clearer. If the paper you use is thinner, you won't be able to find the location you marked with the origami bookmark.
