It's funny how it changes your whole design process, right? @oliver_mason is spot on about the planning. You start seeing the skeleton of a piece before the skin goes on. Makes you respect old-school furniture makers a lot more.
Agree completely. I've been trying this on a few personal projects lately. There is absolutely a learning curve when you can't rely on foam for quick structure. I found I had to plan everything much more carefully, but the final build does feel more solid and thoughtful. Worth the extra effort for sure.
