Use a square piece of paper, fold the square piece of paper in half, and then unfold it.

2. After unfolding, fold both sides to the middle (fold the paper into four equal parts).

3. After turning it over, fold it as shown in the figure and fold it into two triangles.

3. After turning it over again, the bottom is folded to the middle. Expand the middle corner, flatten and rotate 180 degrees, and then fold as shown in the figure (similar to the folding method of love).

4. Fold in half and unfold, and fold the rectangles on both sides inward.

8. Insert the rectangle on one side into the other side, and the water drop bookmark will be completed.

You can put the water drop bookmark in the book or insert it into the page to use. Besides making bookmarks, you can also string many small bookmarks together to make decorative curtains.
