Probably my favorite set of stickers that I've bought are these "Woodland Music Stickers" by Victoria Madsen. Go buy them. THEY ARE AWESOME. It's just a bunch of animals and the instruments they would play if they had any capability of doing so. If you thought a skunk played trumpet, WRONG, it plays bagpipes. Also, I like the stereotypes associated with each instrument. Banjo players are hicks (and...is that a vole?), triangle players are dumb (not true) and pianists are stodgy (true).
