1. Prepare a square piece of paper, fold its diagonal in half and fold the crease.
2. Fold the paper in half, align the vertex of one side with the crease to form a triangle, then fold the triangle in half and fold the crease.
3. According to the method in the previous step, align the vertex on the other side with the crease to form a new triangle, then fold it in half and fold the crease.
4. Fold the two sides of the triangle inward into a heart shape and flatten the creases on both sides.
5. Finally, fold the bottom half of the heart up and stuff it into the gap above the heart to form a bookmark.
It should be noted that every step of origami should be folded smoothly and accurately, and there should be no skew, overlap, gap and other phenomena. In addition, when choosing paper, it is best to choose a tough and soft paper, which will make it easier to fold out the perfect love bookmark.
