Felt bodies coming off the line are probably similar but in the past, these bodies were aged for at least a year before being used. Today, they can't afford to have the cash tied up that long. The felting of that aging process DID produce a better quality felt body to start with in the processing.
I'm not going to touch the possible global warming effect on animal fur because we all know where that will lead....
I can understand that. It is akin to aging wine or whiskey. Since the average global temperatures have been cooling for the past 11 years, I would assume animal furs would have gotten even thicker but probably not enough to matter.
