On a side note, sitting on a hat and getting rumples in it can be fixed by reblocking.
If I am wearing an Indy fedora(I occassionally wear a couple of other fedoras) I like mine beat up somewhat. But, I wear it with casual clothes too. If I were to don a suit, and decide to wear a hat, I would want it to be crisp, to fit with the other attire.
On my own hats once I finish one, I will immediately beat the heck out of it for perhaps 30 minutes off and on as I watch the History Channel. I start with just chopping it with the side of my hands, working the crown and then the sides, all around the crown. I do this for quite some time, softening the felt up. If the hat is still not the way that I want it, I grab the brim brush, and literally beat the hat with the wooden back side of the brush, until it gets to the way that I want it to feel. I then brush it well with my crown brush, and put the creases in. Even when the hat is new, it looks like it has been worn much more than it has, but still has the good fresh blockshape to it. I really don't sit on them, except for the HJ, just to see what the result will be.
Really, if you take one of these new beaver ABs, you can abuse it the way I described and it will just mellow the felt out. You may pick up a little more fuzz on some runs, but nothing drastic, plus the beaver nap has a really nice expensive feel to it. So, you guys who own my hats, don't be afraid to beat em' up. You will not hurt the hat. Just don't go and beat on the ribbon, you may break a stitch, but from the ribbon up, it is open season. With the long method we use to make our hats, the initial blockshape is really set well, so you won't change it by doing what I do. In fact, I think softening up the crisp new blocked hat actually helps it to look better, that is, if you are going for a good Indy look. Fedora
