The hat felted to the approximate size I was looking for, but this is definitely a trial & error process. I ended up with a head circumference too large and a cap length too short. I think I know how to alter my pattern to get what I am looking for, but unfortunately I won't know until after I knit and felt the entire thing. I haven't done much research on this process and wonder if there's a surefire way to guarantee that the finished hat will have the desired dimensions? Anyways I will try again and see what I get!
