Billy,
I have to think about what materials are best suited for the model and how I will construct it. Buildings constructed of styrene have to be reinforced so they do not warp over time. I also think about the sequence of construction and even if I will pre- paint some assemblies or paint all at once. Basically, I will re-invent the wheel for every model. I can drive myself crazy sometimes. Eventually, I organize the thoughts and start kicking a— - on the project.
