Strange but true! Imagine my joy at seeing the rick-rack snip at birth! How unusual I thought! Now here we are 2.5 months later and the rick-rack has disappeared. No idea that markings could change! Hoping it will return to its original form. 
That IS funny…
Maybe it’s because the foal coat is longer, so the snip seems wavey, and in the short summer coat it looks straight.
She’s very cute!
My filly has a small star on her forehead that looked like an “s”, now 1.5 yrs later it is a “j”.
My 2008 Escudo II colt had a perfect zig-zag pattern down the center of his face that straightened as his head grew! It was a beautiful marking, and quite unusual, but it is never coming back!
my black filly started out with a star. Now she has 2 tiny crescents that sit below each other…looks like 2 half moons
My mare was born with a snip and a few white hairs above her left eye. At 6, she has a snip, a small star, and enough white hairs in between you can almost call it a broken stripe.

She gets more white on her face every year. I keep joking she’ll have a full blaze by the time she’s 20…
Disappearing markings and now we have Texarkanas mare with the expanding face markings!
That gives me hope that my filly will sprout a belly spot. Wish mine all had one of those! I have one with 4 belly spots that look like ink blot mirror images. Also has a spot between jaw bones. That horse accumulated all of the missing belly spots from the other horses lacking one. 
The white almost always gets smaller as they shed their foal coat (and also as they grow). The longer foal coat hairs expand the white markings and you lose a lot of that with the loss of the hair.
I have one mare that was recorded as having NO markings at her inspection at 5 months old. As an adult, she now has a very wide star/connected stripe of white hairs down the front of her face. It is not as obvious as normal white markings, more like roaning, but it is interesting that she did not have one single white hair on her at 5 months old (and she had already shed her foal coat).
