For my money you can't do any better in the bow tie department than The Cordial Churchman. Andy, the actual cordial churchman, posted a bow tie his wife Ellie made for him. A bunch of us immediately responded "Gimme," and a business was born.
I call these outfits "cottage artisans" — including Kent Wang and Sam Hober. Good stuff, and reasonably priced.
I'm sure I am forgetting someone. Feel free to add your faves.
Nothing against Beau Ties, Maine Bows, et. al. I have plenty of ties from them too.
