Tutorial on stacking cup flowers

1. First, spread out the reverse side of the napkin, as shown in the picture.

2. Then fold the napkin in half horizontally and vertically along the center line, and then fold the left and right sides in half to the center line. As shown in the picture.

3. Press the center with your fingers and open the upper and lower sides into an "eight" shape. As shown in the picture.

4. Roll the lower part to the middle line. (Be careful to pinch it tightly, it will be more beautiful)

5. Push and pinch the other end. As shown in the picture.

6. Then fold it in half along the center line and hold the lower part with your fingers. Insert it into the cup so that a beautiful butterfly folds out, completing the rendering.
