First off, thank you! I wasn't there for the FNL but yes, I did all the decorating excluding the Medical Bay (props to Captain Unohana). I really had to push it because our hall got moved to undersea 2 days before the FNL and I didn't want our hall looking bare for the show. You have to be a member and given permissions to decorate a league's hall. A friend of mine asked me to decorate his so I had an alt to do just that!
Might grab some shots of my "Cavern Tavern" later and post them. Most of the work was done last year, but I added a couple of new things this year.
