My other favorite is the one that I built this year, which I'd been wanting to do for ages and will continue doing as a hobby and maybe eventual retirement activity. It has a ton of mistakes but feels special knowing how it all went together.

My favorite subreddit was r/Luthier, I just started up an equivalent community here, although given current user base I'm guessing all discussion will happen here on guitars until we're able to support more niche users like that.
