2. Take out a balloon of the same color and stick double-sided tape on one third of the balloon.
3. Glue another balloon of the same color to the balloon in front. Glue four balls of the same color together, as shown.
4. When the last ball of the same color sticks, pay attention to enclose five balls in a circle, as shown in the figure.
5. In the last step, put the blue ball on five red balls and compare the positions. Stick double-sided tape on one red ball to fix the blue ball.
6. Because only one side is attached, the other sides will be inclined. Turn the balloon around and see that the inclined part is stuck by double-sided tape.
7. Select a few ribbons and tie them together with lines, as shown below.
8. Finally, turn the flower balloon over and tie the ribbon just tied to the bottom of the blue balloon, as shown in the figure below.
9. The ribbon below is straight and not bent. You can draw the ribbon, scrape it with a wallpaper knife, and the ribbon will bend immediately, thus completing the balloon flower. Just tie the ribbon directly to the handrail of the stairs.
