The manual wrapping method is as follows:

Material: yellow cardboard, double-sided tape and scissors.

1. First, take a piece of yellow cardboard and fold it in half. Fold the long sides inward about 1.5cm, and fold a triangle inward at the position opposite to the fold line, and synchronize up and down.

2. Then stick double-sided tape on both sides folded inward, and then fold it in half and stick it together.

3. Continue to cut two strips with yellow paper and stick them at the opening of the bag.

4. Then draw flowers and branches of various colors and shapes on white paper and cut them.

5. Finally, paste the cut flowers on the bag and make the bag by hand.
