My trainer does an anual halloween show at her barn and always adds a costume class! This year, I am going to use my Chincoteague Pony, Piper, in it and have our idea and everything picked out: My brother is going to help me and he and I are going to be "Thing 1 and Thing 2" and we are going to turn my pony into the Cat in the Hat (from Dr. Seuss's book). But, my problem is that my mare is a buckskin, but she needs to be turned black. I know that there are many horse body paints out there and all, but I'm wondering if they will stain her b/c she's so light and the paint color is so dark. Does anyone know of a paint type, etc. that I can use on her safetly? Thanks!!
