First, forgive me if this is not the most appropriate forum for this question (and Mods, please feel free to move the thread if you feel it should be).

In a few months, I'll be a Groomsman in a wedding party for my brother-in-law.
The dress is Highland Formal (Black tie, Prince Charlie, etc), but I'm curious for opinions on my plan for sporran.

I will be making a new sporran for myself for this event. I'm not a big fan of tassels in general, and have never included any on previous sporrans I've built (all of which would be categorized as either day wear or rustic), but I figured it'd be nice to make something a little more formal-looking this time.

I have this skunk pelt which I've been wanting to turn into a sporran for a long time, but I was thinking of using a trio of Ermine tails for (or in place of) tassels.

So, tell me; is this a ridiculous faux-pas, or am I creative genius?
