I just recently purchased this randomly:
http://www.cosplayhouse.com/Touhou-Project-Cosplay-Accessories-Marisa-Kirisame-Hat.html

The quality is honestly what I'd expect from a $20 hat, but it's a Marisa hat and I'm quite happy. Wearing it right now actually biggrin
Then I started thinking...why hasn't anybody started producing touhou hats for mass production to be sold to the fans?! They're awesome headgear and I'd love to buy a Hong Meiling hat.
Does anybody know a good person/place I can go to ask to manufacture a Meiling hat? Also touhou hat general. What's your favorite touhou hat?
