don't know why i never thought of this before. had an audition yesterday and there was one particular song i kept flubbing while practicing it in the house. didn't want to bring along any notes and realized I could could write my notes on the bottom of my left thumb (and that whole area of my hand and wrist if needed). just kinda looked like a weird tatoo, and nobody even noticed. it worked in college on spanish tests, and still works now . just thought i'd pass that along.
