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!
LOVE.
This!
I used to play the sousaphone...wonder how much worsted yarn that would take... :D Excellent, excellent and excellent!

A- shove more yarn in the bell and miss most notes
maybe i should con my girlfriend into knitting me one of these for the colder months...
sorry for the sarcasm, but it seems you haven't been on instructables for very long.
