CraftyDeb, you are frikkin' AWESOME.
It had never occured to me to knit the stupid thing!
I worked it up last night and stuffed it, and it's light, and adorable, and sturdy. THANK YOU. I got even got a picture, which is fuzzy and tiny but it conveys the general idea:

Exeter Flud, I tried elastic with the paper horn, but it didn't work out. It made the dog go nuts trying to get the horn off. Maybe it pinched him.
I'm thinking maybe some clippies underneath...?
