What are the folding methods of ancient bookmarks?

The folding method of antique bookmarks includes preparing a square colored paper, a pair of scissors, a pen and a bottle of glue for later use. Then we fold the center line of the colored paper in half and continue to fold the center line of the colored paper in half again, as shown in figure 1. Draw a quarter circle on the folded paper. Don't draw it too big, or it won't look good.

With the popularity of "retro" beehives, quite a few articles tend to be antique. The existence of ancient book bookmarks can add ancient rhyme when reading, so it seems more eager to read. Antique bookmarks are divided into many different types, one of which is card-type, and you only need to print the pictures on the network to the card. Of course, you can also hang your ears and write poems on them, which will look more beautiful.
