Musical Stave Ruler

A five line stave ruler for musical staff. It's designed for a B5 notebook, but you should be able to use it on bigger notebooks. It'll be easier to draw lines without bending the ruler. Try holding only a finger down on one end while making lines. You can add a tassel or a keychain to the end of the ruler.I tried to make the stave lines closer but the teeth started bending.Let the ruler cool before peeling it off the bed.
