I posted this in tanning...thought someone over here might have answer too....I have a mule deer I recently mounted. The customer commented that the neck looked way small. Looking at pics he may be right. I know he brought the deer to me apx 4 days after he shot it without ever putting it in the freezer. Not sure why it didn't slip. Anyway, could this be a cause of shrinking? Or, is it something I've done? I use Lutan as I always have. The other two whitetails I did for him in the same group came out just as they expected...all tanned at the same time.
