I know you are super-sensitive because of what happened with the blankets, but if you have ideas for bells, you go girl, and you make them!
One thing to consider when designing them, is something that won't bang the door. I threw one together for Chloe, and it was just a jingle bell on a wide ribbon, and it flaps in the wind and bangs the glass slider we hook it onto. But if you can find a way to make something that doesn't bang the door its tied to, that would be a plus.
I can't wait to see what you come up with.
