I have a show coming up in two weeks and I need to throw together a horses Egyptian costume. Mine is ready. Not a mummy or anything like that, but like a horse Cleopatra would ride to patrol her kingdom. (I'm going to be Cleopatra.) Last year I was an Indian and Ebony was painted to be an Indian war horse. I am going to make a blanket out of "gold" with tassels on it but I need more than that. Thank you!
Have gold tassles hanging all the way along your reins. Buy some of that horse glitter/sparkly stuff for her hooves, mane and tail. Buy a few rubber snakes and incorporate that in your costume somehow (you have one draped around your neck, attach one or two to your tack) (Remember that is supposedly how cleopatra died, suicide by snakebite).
Does that help?
