This is a set of labels I created to allow me to label the bars of my Orff mallet instruments using the colors of the Boomwhackers. C is red, D is orange, etc. The template is designed to use Avery Easy Peel Mailing Labels, which are product number 18160 (template 5160). Each label can be cut in half since most Orff instruments only have two of any given note. There is also an option to use a different label to indicate high C/high do. These correspond great with my Boomwhacker Powerpoints!
