Oops, I called her 'Angela Walters' and it's Waters, not Walters...
One thing that will help you more than anything with your movements is to get a doodle pad and draw the kinds of shapes and movements you like. Meander on a few sheets of doodle pad with a marker. In fact, before I try any new design I always doodle it out first to gain my confidence. There isn't a lot of time to think about where you are going next while FMQing, so practice by doodling to get your design set in your head and hands first.
