Eeek! KittyBethy, I was afraid of that! Is there truly no other MLP w/ "white witch" hair? Over on the "Wanted" thread, PandaBerryInSpace suggested I just buy some hair from DollyHair, which I'm considering, but this Minty is just about mint, and I hate to not use a vintage tail.
I always thought Twilight's hair looked like it has a bit of silver in it, but is her hair Virgin Snow? Unfortunately I don't have one to compare to at the moment.
As for what happened to Minty's original tail--it had been threaded very badly at the factory w/ lots of loops of hair at the top of the tail. I was trying to fix this, and large chunks of tail starting falling out. I've never seen anything like it! I'm very careful not to pull too hard on tails, but this one self destructed!
