Before the lantern metal frame built, we know that creating a custom lantern is more complicated than it seems. First, we decide on the theme, then work on the design, and finally, we have to turn a 2D drawing into a real 3D lantern. This takes teamwork and careful work—especially when welding the metal frame. Every small part must match the design perfectly. But how do we make sure the final frame looks just like the plan? The answer: a trial assembly! This step helps us check if everything fits before the final build.
