    I grew up in a small Midwestern town where weekends meant sawdust on my jeans and the sound of my dad’s old table saw running in the garage. Woodworking became my favorite way to unwind long before I ever thought about turning it into a career. Over the years I’ve built everything from simple shelves to full backyard pergolas, and I’ve picked up plenty of mistakes and lessons along the way. I started Woodwork Insights because I wanted a place to share those lessons in a way that feels honest and useful. My projects aren’t perfect and I don’t pretend they are.
