For the Nazis out there who like building things-and you should,because we're White,and that's What We Do-a very useful item is the pocket hole jig.

The pocket hole jig is a simple,but very effective way of joining two pieces of wood together. And since most of the required precision (and skill) is built into the equipment,you can be a beginner,a very-part-timer,or just a plain klutz. And still get results that are acceptable,if not exactly spectacular.
So the next time you need a set of shelves,a kitchen island,or a cabinet of some sort,remember that there's an alternative to IKEA,or garage sales. You can go buy some tools and some materials,and build it yourself.
Will you be able to beat Chinese slave labor prices?
Probably not. But what you can do is come close to Chinese slave labor prices,and wind up with an artifact that does what you need it to do. And,in the process,learn how to do something you didn't know how to do,or get better at something that you kinda sorta knew how to do already.
