The kids can lead the music using the scarf. I made a tube with fringe for the scarf, cut a hole in my tri-fold display board and glued the scarf to the back side of the board. The backs of the snow flakes have songs on it also.
I can't take credit for this idea though, well not all of it. When I was in Primary, my mom made one that was an elephant and you got to lead the music with his nose. And there were peanuts on the display that had songs on it. My mom has some of the best ideas like that. She's pretty cool.
(I'm kinda buttering her up to watch my girls on night next week when I am down visiting)
