I Built This Wrong. I’m Glad I Did.

Avoid common beginner woodworking mistakes with insights from personal experience on building and repairing furniture.

More than 20 years ago, before The Wood Whisperer and before I had much experience in the shop, I built this country bookcase for my mother-in-law. It was probably the third piece of furniture I ever made. After several moves and more than two decades of use, it finally came back to my shop for a few repairs.

That gave me a rare chance to look closely at my own beginner woodworking. Some things held up much better than I expected. Other choices, including poor back-panel construction, cross-grain assemblies, sanding mistakes, and a few shortcuts, caused exactly the kinds of problems I now warn other woodworkers about.

Rather than trying to make the piece look new again, my goal is to fix the structural problems, replace the missing back boards, match the old finish as closely as I can, and let the bookcase continue showing its age. This repair actually inspired a new article I wrote recently: Is Traditional Finishing Dead?

Looking at an early project like this is a good reminder that woodworking skill comes from experience. You can research techniques and watch videos all day, but eventually you have to make some cuts, build some furniture, and give yourself permission to make mistakes. Twenty-two years later, I can see plenty of things I would do differently, but I also know I needed to build projects like this to become the woodworker I am today.
