Based on the limited information, making a packing box involves these key steps:
- Start with a pre-cut cardboard sheet designed to be a box. (This is assumed since the video starts after this step.)
- Fold the smaller flaps inwards. This action helps support the sides of the box, giving it structural integrity.
- Continue the folding process. (The video snippet stops here.)
It can be inferred from this information that creating a functional packing box involves strategically folding and securing the flaps of a pre-cut cardboard sheet. Further steps, not detailed in the provided snippet, would likely include folding and taping the longer flaps to fully enclose the box.
