The black one is the basic model, not tricked out at all. The cowhide one needed an insert of heavy leather to make it stand up. I didn't need one for the top, it seems happy without anything. If you wanted to you could make a "sock" to go over the basic model and change hides and such as you desired. I did one with cow horns, very "medicine man" looking things. Kids loved that one.
Two notes. I did the lacing for the crown and top inside out, and then reversed it. It's a heck of a lot easier that way. And as I noted elsewhere, the brim has two more holes than the crown, at least on the large version.
AND, there will be envelopes mail in the AM, I was hung up at the VA longer than I liked, but I have the promised copies for everybody in hand.
