Okay, here's the story on the tapestry (and basically, this storyline in general):
Years ago, I was watching The Tudors (the show about Henry VIII and all his wackiness). While I was not too impressed by the show itself, one image stuck out in my mind. It was the mass execution by hanging of an entire village of people. Of course, given my sick mind, the only thing I could think at the time was about that damn cat poster where it says "hang in there". I thought, if anyone was going to create anything inspirational out of that senseless tragedy, it would be Henry VIII. And I basically crafted this storyline to find a way to introduce Sluggy's tapestry.
