Method:
1. Prepare scissors, colored ropes and gift boxes. Prepare a ribbon, the length of which is 4 times of the total length+width+height of the box.
2. Leave the necessary length for bowing, then make a circle vertically, prepare a ribbon long enough, and put the ribbon vertically on the gift box. Then put the colored rope on a third of the foam board and wrap it around.
Then wrap it on the other side of the gift box. The heads of two colored ropes cross and then wrap around the other side of the gift box. As shown in the figure below.
4. Pull the ribbon back to the front from the bottom of the box as shown in the figure.
5. Then press with your fingers and tie a knot through the colored rope here, as shown in the figure below.
6. Then tie a bow. Trim both ends of the belt into the desired shape.
