Seriously, probably watching the guys on TV that make it look so simple
because they can build a curio cabinet in a half hour show is a good place
to start.

Half the battle is having the right tools. I suggest starting with something
simple like a book case or night stand. Use Pine since it is soft & somewhat
forgiving ( easy to sand anyway) . Birch plywood matches it pretty well if
you want to use it for the carcass. That's where I started.
