Better quality for less money? No. You do woodworking (if in fact you do) because you enjoy it. The time spent making a decent piece of furniture you could work at McDonald’s and buy a nicer piece in less time it takes to master woodworking.

So, don’t kid yourself! You enjoy it, and if you’ve mastered the skill then naturally you can save money over time. But I’d wager you spend more in hours mastering the skill than if you were to buy a couple pieces of furniture. ;)
