This medieval hat is made in the style of a chaperon
It was made for me around 1990 for medieval theatre style reenactment at Warwick Castle for group called Knights Errant.
Errant Knights being knights with no particular lord that wandered the country looking for adventure, duels, jousts, or just pursuing the values of chivalry.
Made from a platted band of brown, red and white wool forming the bourrelet around the head and separate wool cornette lined with linen, it forms a very comfortable simplified chaperon style hat.
I've worn this hat many time, for many characters, its still worn today and in excellent condition after 25 years of life.
