The 11 inches is measured from around one right down to you attain 11 inches. So lay it out on flat floor and degree from the place you first started because of the undeniable fact that would be the crown of the hat and are available down the scale which would be coming down in the direction of your face and once you attain 11 inches then it sounds such as you would be including a brim to that. yet from the crown it is the place you started and are available down in the direction of the face .
