Nova's forehead swirl
Sounds like Ms.Tellington-Jones is pretty spot on!
Here are some photos of all Nova's other cowlicks. Remember folks! Cowlicks can be used for identification, so take pictures of them to keep in your record! Also I suggest doing the same thing for your horse's chestnuts. If it may ever happen that your horse is stolen, having all of this identifying proof will be helpful in getting your horse back.
