I'm in the process of trying to find patterns or someone who is able to make two kinds of hats common throughout but specfically for 16th Century. One is a phrygian cap and the other is called a crooked eared cap.

I've found two version online from people who sell them, one was a phygian cap with the bend already made, my crew calls them the shark tailed hats mainly because one of the colors was grey. The only is felt but is limited in size and doesn't bend at all.. is completely a gnome looking hat

As for crook earred hats the drawings I've found make it look like a coconut with ear flaps

Also my crew is looking for a source for someone who makes tams and larger sizes on the hats the Irish at Southern wear (I lovingly refer to them as the dutch cocoa pimp hat)
