The Warmest Euphonium in the World!

I made a cosy for my euphonium (a half-size tuba) to help keep it warm. I used exactly 245 meters of worsted weight yarn, and used mainly knitting to cover it, but also did some basic wrapping around some of the smaller slides, as there is not much space in between them. Even with its new coat, my euphonium is completely functional, and certainly demands a little more attention than it used to!
