Why I Started This

I used to dread going back to the shop. Every session was interrupted — figuring out the next cut, rechecking a dimension, second-guessing a measurement. Then I built myself proper plans, and everything changed. It felt like building a Lego set. My wife noticed before I did: I was having fun again.

That's what Peterson Plans are — plans that let you enjoy the build.
