LEFT: Too wispy; piebald edges should not have such long bits of fur straying off the white.
RIGHT: Overly-blurred edges; the edge of piebald needs to be more defined.

LEFT: Too feathery; a mix between wispy and blurry -- piebald edges need to be defined.

RIGHT: Too spotty; the edges should not be overly-complex or have so many tiny spots.

Perfect!

Contrary to popular belief, piebald in Tokotas does not follow the rules of piebald in other animals. 
The example below resembles an overo horse. The mistake here is that instead of making a layer
of white and erasing, I just drew some white shapes onto the coat, which is not correct.

Piebald can have some isolated white spots, but keep in mind that it
still needs to flow well with the design and have a natural look.

What not to do:

Large, random spots
Spots are too large and just stuck randomly on the base.
They don't flow well with the rest of the piebald.



Irregular, unnatural spots
Spots are too polka dotted, linear or stripey.


Avoid imitating other markings like bearmarks or rainmarks by creating isolated spots, as this is not acceptable. 

If your design looks like patches of colour on white, you've done it correctly!
If it looks like patches of white on color, it is incorrect.
