1. Take a square piece of handmade paper, fold it in half on both sides, fold the middle line upward for a parallel section, and unfold it to get three creases.

2. Fold the other two sides in half, fold the center line upward for a period of time equal to the length in the first step, and then loosen it. Then fold the center line in half and a small square appears in the lower corner. Fold the bottom corner of the small square upward, fold the upper corner into a crease, and then loosen it, and unfold the whole paper to get the following pattern.

3. Fold the two center lines in half, and the small square in the middle will press down a center line, and then press down. Put the square down and line up the four sides.

4. Turn the paper over, pull up one side of the crease at the midpoint, overlap the next fold line along the line pressing direction, and press out the crease.

5. Press out the creases on all sides and turn them over. The intersection of crease and polyline is a, and the intersection of small square and another polyline is b, and the two points connecting AB are folded to make traces.

6. Turn it over again and get the following. Rotate the flowers slowly along the crease.

7. There are four pieces at the tail, one piece is buckled, and the last piece is buckled into the starting piece. There will be a rose, arranged in patterns and curled.
