I was a majorette also! I started when I was 8 and twirled up until I was 15. My high school didn't really have majorettes in the band and I was way past the rec level that I was participating in. So I stopped twirling and continued on with my cheerleading. (I did both during the same time periods.)
I don't know much about scholarships, but I just wanted to respond to the thread to wish your daughter good luck. I had lots of fun and went to lots of competitions around the USA. I still have all my batons, knives, flags...and whatever else we twirled! And I still have all my awards displayed in my old room at my parent's house!
