7 Yi 12 years old manual craft small production

I want to make a small handicraft technique for 7- 12 years old:

1. Determine the theme and collect the materials.

2. Design and draw detailed production drawings.

3. Make it step by step according to the drawing, and make necessary debugging and improvement.

Through this exercise, children can improve their hand-eye coordination and logical thinking ability, and cultivate their interest in science and technology.
