Keychain Case?

I am looking for a good way to attach my clip to my keychain and also protect it, but I have not been able to find any commercial products for this purpose.  Has anyone found a good way to do this?  Thanks for any help.

I have a cute leather case that has a metal loop on the side, to attach the Clip to other things.  Got it on from i-nique out of the UK.  It doesn’t seem to be made anymore, however, and also leaves the top and corners of the Clip exposed–don’t know that I’d want that around keys …

How about using one of the ever-present silcone cases, putting a small piece of clear plastic over the display before putting the case on, and then clipping something onto the Clip’s clip?
