I had it done by some friends who own a archery&taxidermy shop. They put some leather on the top which is holding the beard and also braided the leather thru the spurs and they hang down with the beard.
Roman, it looks like they put felt on the back side of the cape,then glued the larger circle of leather with the beard and spurs. Then glued the smaller leather circle on over the beard and braided leather holding the spurs. They just got a web site going recently but they have been doing this for over 20 years. www.stearnsarcheryandtaxidermy.com/
