Hairstyles for Mules
(Most mules tails are not thick enough to make bells this full. These are exaggerated for illustration purposes.)
The same mule's head and neck was used as the template for all of these hairstyles.  The way the hair is trimmed will change the appearance of the head and neck.  An animal with a thin neck (as this template) may not look so good with a roached or tight-braided mane, whereas the banded mane draws attention to the mane and not the neck, and the stand-up manes add shape to the neck.
