In the midst of getting ready for last year's San Jose Renaissance faire, I was fortunate to borrow an adorable Edwardian tricorn brim block from Wayne Wichern. According to our friends at Wikipedia, the Tricorn hat was first noted in 1667 by Spanish soldiers.https://en.m.wikipedia.org/wiki/Tricorne.
1667 is a little late for many Renaissance festivals, but pirate themes are really popular and fun! Not to say there weren't pirates in the late 1500's, but they probably weren't wearing the tricorn hats we all know and love.
The block I borrowed was a smaller brim, and more of a ladies size. Of course, a brim block isn't necessary for making a tricorn, but this one was so cute I couldn't resist.
Next: Navy! I think a cockade would go well with the tricorn....
