no plans = No mistakes

In a way that's right. Some things just can really be visualized until you have the material and tools in your hands. And if there is a mistake, it is fixed along the way rather than trying to figure out what's wrong with a plan.

You know how they say "dont cut towards yourself"?

There Not Jokeing!

Perhaps when this is all done you could create a plan by reverse engineering what you did. Maybe even in the form of a white paper. I think many people could benefit from this neat "at home" project.
