Monmouth caps are historically accurate from the 15th -18th centuries depending on your persona and region.
This is my take on the Monmouth cap. I knit them out of 100% natural wool (which means they are not dyed) These caps are not felted. I have them on hand in a variety of natural colors and sizes. I also do custom color orders on request. Let me know your head size and I'll send you a photo of what's available.
Caps are $35 which includes shipping via USPS.
