Recorder Mute with hole

I love the recorder mute that rodrigo_rc posted, but wanted to be able to attach some sort of string so that my students could easily attach it to their recorders and not lose it when they aren't using it because, let's face it...3rd graders aren't known for being able to keep track of things!

Anyway, all 3rd graders that I teach will be getting one of these along with their recorder this year and I can't even tell you how happy the parents are that this was designed! Hope you all enjoy it as well!
