Currently, finally the feeling of "wonna-have" overwhelmed me in case of a tricorn. There are straw-tricorns sold in the Internet, but buying hats online is as risky as buying shoes, but during a medieval fair I found a store with historical authentic clothes. Had to do some corrections, howsoever, to give it a tighter form; originally it was very loose and wide, but for humble 9 Euros, what can you say?
Actually, in the 17th and 18th century, most tricorns have been made of straw, as farmers, craftsmen and traveling people have worn them as well as noblemen and merchants, soldiers or parvenus. Most sailors had the straw version as well, though their were cheap, a good sun blocker and not as heavy as those made of natural wool.

What I am going to do with it? ... 0o ... Good question. It will be used during garden works, or something like that...
