Going to give you a serious answer and say don’t do a sign. You probably won’t be allowed to bring it in and you’ll just block the view of other spectators. Yell her name and number while she’s on stage. Have her post competition cheat ready for her when she steps off stage. And make sure you get tons of pictures of her alone and with everyone that came to cheer for her. My biggest regret is always being so tired and hungry that I forget to take more than a few pics throughout show day.
Good to know! Thank you
